3Changes in 1.2.18 (2015-03-10):
4
5* aven: Add a menu item and toolbar button to show the cavern log window if the
6  currently shown survey data was processed by aven.  Reported by Hugh St
7  Lawrence in #47, and by Dave Clucas and others previously on the list.
8
9* aven: Add "Save Log" button to Aven's cavern log window.
10
11* aven: Add "Colour by Gradient" and "Colour by Length".
12
13* aven: Make the button to dismiss the "About" dialog "OK" rather than "Close",
14  which seems more logical, and also allows the dialog to be closed by pressing
15  "Escape".
16
17* aven: Don't round bearing and tilt angles to integers when printing and
18  exporting.
19
20* aven: In cavern log window, highlight "error" markers in red and "warning"
21  markers in orange.
22
23* aven: Aven's support for reading colours and font sizes for printouts from
24  print.ini has never worked - the contents of the ini files are ignored due to
25  a bug which has been there since the code was added in 2005 - but nobody has
26  ever complained.  So just strip out that code entirely - we should support
27  setting the colours and font sizes, but a GUI interface for setting them
28  would be better.
29
30* aven: Rework code to read cavern's output.  In particular, we no longer mix
31  buffered I/O with select() on the file descriptor.
32
33* aven: Fix to compile with a Unicode build of wxWidgets 2.8.  Reported by Bill
34  Gee.
35
36* aven: Add JSON export.
37
38* cavern: Use the currently set units when outputting measurements in warnings,
39  errors, and the stats at the end of the run.
40
41* findentrances: If the 3d file specifies the coordinate system, use it.
42
43* (Microsoft Windows version): Add code page 1252 mappings for fancy quotes.
44
45* Transliterate gradient and infinity symbols if the current character set
46  lacks them.
47
48* Add SVG version of .plt icon.
49
50* cavern: Warn if fore and back measurements differ by more than 3 SDs, rather
51  than just by 2 SDs.
52
53* doc/manual.sgml: Add complete list of quantities you can set SDs for.  Thanks
54  for Wookey for highlighting that the previous list was incomplete.
55
56* doc/manual.sgml: Document averaging of a group of repeated readings.
57
58* doc/TODO.htm: "Save cavern log from aven" now implemented.
59
60* cavern: Include column number when a *include file isn't found.
61
62* cavern: Show 'error' in front of error messages, like we show 'warning' in
63  front of warnings.  Fixes #48, reported by Wookey.
64
65* If we run out of memory while reading a processed survey data file, include
66  the filename in the error message.
67
68        * lib/: More translation updates.
69
70        * lib/el.po: Fix language code in file to be 'el'.
71
72        * lib/hu.po: Change '...' to ellipses.
73        * lib/hu.po: Add missing quotes.
74        * lib/hu.po: Use curly double quotes.
75        * lib/hu.po: Remove erroneous quotes from message.
76
77        * lib/ru.po: Merge more translation updates from "vsuhachev".
78
79        * lib/id.po: Merged translation updates from "Cave ID" - all messages
80          are now translated into Indonesian!
81
82* doc/manual.sgml: Document averaging of a group of repeated readings.
83
84        * doc/TODO.htm: Update.
85
86Changes in 1.2.17 (2015-02-24):
87
88* MacOS X version:
89
90  + Update INSTALL file with current status.
91
92  + Aven.app now has a custom icon.
93
94  + Add icons for all the filetypes supported.
95
96  + Add Finder actions for .svx, .3d, .plt and .pos files.
97
98  + aven: Hide the status bar and tool bar in Full Screen mode, as wx doesn't
99    currently do this for us.
100
101  + aven: Fix short-cut for toggling Full Screen mode.
102
103  + aven: Make "About" menu item appear.
104
105  + aven: Fix "Close" button in about dialog.
106
107  + aven: Make custom cursors black with a white outline to match the standard
108    OS X cursor.
109
110  + svxedit: Now wrapped up in an application bundle as svxedit.app.  It
111    still doesn't really work like a standard app though - e.g. you can't load
112    files from Finder (instead run svxedit.app and use File->Open), the font
113    size of most menu items is wrong, the icon for the app is the wish icon
114    rather than the svxedit icon, shortcuts use Ctrl not the Cmd key, and
115    probably more.  I'd probably recommend using another editor (OS X comes
116    with TextEdit.app for example).
117
118  + The documentation is now in a "Docs" directory alongside the apps, rather
119    than in the rather less obvious "share/doc/survex" directory.
120
121  + Default to building for x86_64, since all modern Macs are 64 bit.
122
123  + Disable use of liblzma when building wxWidgets for OS X, which was
124    preventing the build from working on OS X 10.6.8.
125
126  + Download wx sources from SF via redirecting link.  Thanks to David A.
127    Riggs.
128
129  + buildmacosx.sh: Handle the mount point for the disk image containing a
130    space.
131
132  + Link with a static build of PROJ for doing coordinate system conversions.
133
134  + Build wx with --disable-webview to avoid a compilation failure on OS X
135    10.10.1.
136
137  + Use wx-config --cc and --cxx to get the compilers to use for building
138    everything else, as wx adds options to them which otherwise cause linking
139    errors.
140
141  + The diskimage (.dmg) file is now compressed with bzip2, which gives a
142    smaller download.  This means OS X 10.4 is required, but we probably
143    already need at least 10.5 because that's the minimum version which the
144    wxWidgets build supports by default.
145
146  + Remove unused files and copies of files from the diskimage.
147
148* cavern: If the same leg is repeated consecutively, average the readings and
149  treat as a single leg.
150
151* dump3d: Report SEPARATOR used by the file being read.
152
153* aven.svg: Fix visual glitch in SVG icon for aven.  Noted by David A. Riggs.
154
155* aven:
156
157  + Greatly reduce flicker when mouse is moved to the top of the screen in full
158    screen mode and the menu bar reappears.
159
160  + For export formats where scaling is supporting, aven now actually uses the
161    scale specified in the export dialog (previously it ignored this and used
162    1:500).
163
164  + Reimplement animation so that it's based on angular change per unit of
165    elapsed time, rather than averaging the time take for the last two scene
166    redraws.  This gives smoother animation in the face of variable load and
167    scene redraw time, and should be more consistent between platforms.
168
169  + Switching to a point of the compass during auto-rotation now jumps straight
170    there rather than the two animations fighting.
171
172  + Reduce the maximum auto-rotation speed, as the previous limit was uselessly
173    fast.
174
175  + Disable stepping the rotation angle when animating (previously we only did
176    when rotating).
177
178  + Speed up start-up a bit - rather than loading icons from individual PNG
179    files on disk, compile them into the aven binary.
180
181* (Unix version): Add "MimeType" field to desktop files so that file
182  associations work out of the box with modern desktop environments.
183
184* Add start of Hungarian translation from Imre Balogh.
185
186* Merge in many updates to the Russian translation from "vsuhachev".
187
188* Assorted minor updates to other translations.
189
190* Create scalable (SVG) versions of file type icons.
191
192* doc/manual.sgml: Remove $Id and $Date markers, as they don't get expanded now
193  we're using git.
194
195* tests/: Improve test coverage in a few places:
196
197  + Extend tests of fore and back sights to test calibration of the back
198    compass.
199
200  + Test "Can't calibrate angular and length quantities together" error.
201
202  + Check that "*set names ." works when "." is also the decimal point.
203
204Changes in 1.2.16 (2014-10-17):
205
206* aven: Add KML export (stations only currently).
207
208* aven: Allow measuring line to measure from anonymous stations.  (Fixes #44)
209
210* aven: Fix corrupted names in exported files.
211
212* aven: Fix error log window under wxWidgets >= 2.9 to include the system
213  information before the first log message like it does under wxWidgets 2.8.
214
215* cavern: Add support for "*cs JTSK" and "*cs JTSK03".
216
217* tests/: Improve test coverage.
218
219* Translation updates for many languages, plus the start of translations to
220  Greek and Polish.
221
222* Fix to build against wxWidgets 3.0 built with assertions disabled.  Reported
223  by Martin Sluka.
224
225* Fix warnings when compiling with clang (which is the default compiler on
226  Mac OS X).  Reported by Martin Sluka.
227
228Changes in 1.2.15 (2014-08-14):
229
230* cavern: The *cs command now also supports "long-lat", "s-merc" (for "Web
231  Mercator"), EPSG and ESRI codes, "eur79z30", "ijtsk" and "ijtsk03".  This
232  means that we now support all the coordinates systems which Therion does,
233  except for a few which don't have X=East and Y=North.  The documentation
234  for *cs has also been improved.
235
236* aven: We no longer persist full screen mode between runs - it's not a
237  standard behaviour of desktop programs, and it's too easy to go into full
238  screen mode from the menu and then not be able to get out again because you
239  don't know the required key shortcut. (ticket#39)
240
241* aven: When in full screen mode, moving the mouse to the top of the screen now
242  makes the menu bar appear.  This provides a non-shortcut way out of full
243  screen mode, as well as making it easier to perform other operations while in
244  full screen mode.  The current implementation gives an annoyingly flickery
245  transition, but hopefully we can improve this in future. (ticket#39)
246
247* (MacOS X version): If built with wxWidgets >= 3.1.0 (which is still in
248  development), we now call EnableFullScreenView() which improves the full
249  screen mode experience on OS X 10.7 and later.
250
251* img library: Improve documentation for img_ERROR_INFO.
252
253* tests/: Ship some missing .out files and compare.tst.
254
255* tests/: cavern.tst testcase back2 is now actually used.  Fix a bug in this
256  testcase, and extend it to cover a variant of the situation reported as a bug
257  in therion by Bill Gee to the therion list.
258
259* (Linux version) survex.spec: Add run-time requirement on proj and proj-epsg
260  for the survex package and on tk for the svxedit package.
261
262Changes in 1.2.14 (2014-07-05):
263
264* img library: Add ability to store a PROJ4 string describing the coordinate
265  system in use in 3d v8 files.
266
267* aven: If the 3d file specifies a coordinate system, then use it for exporting
268  to formats which need to know (currently GPX).  If the input file doesn't
269  specify the coordinate system, allow the user to enter a PROJ4 string in the
270  export dialog.
271
272* aven: You can now quickly zoom to a particular area by holding down the
273  "Shift" key and dragging with the left mouse button to create a rectangular
274  "rubber band box" around the area you wish to zoom to.  If you release the
275  "Shift" key while still dragging, the box is centred on the start point
276  rather than having one corner there.
277
278* aven: Fix exporting of passage tubes in elevations and extended elevations
279  - previously up and down were getting drawn across the page!
280
281* aven: Fix "Cancel" to work on the print/export dialog, broken by changes in
282  1.2.13.  (Reported by Brian Clipstone)
283
284* aven: Fix the conditions on which the menu item "Cancel measuring line" is
285  enabled - previously it was hard to actually cancel it via the menu.
286  Reported by Hugh St Lawrence.
287
288* aven: Fix wx assertion failures when showing hit test debug view on platforms
289  such as 64-bit Linux.
290
291* aven: When viewing from above, show "Plan" above the "clino" which indicates
292  the tilt angle (instead of "Elevation -90°").
293
294* aven: The extended font data now loads faster, and also uses less memory on
295  64-bit platforms.
296
297* aven: Dragging the vertical divider between the side panel and the 3D view
298  now only updates when you finish the drag, as redrawing continuously just
299  looks clunky except on an ultra-fast machine.
300
301* aven: (German translation) Abbreviate "Blickrichtung" so it doesn't overfill
302  the space available in the aven UI.
303
304* cavern: Add a *cs command to allow setting the coordinate system for *fix
305  commands, and the coordinate system used for processed survey data.  The
306  latter is now stored in 3d v8 format files.
307
308* cavern: Add support for 'L' flag (exclude from length) in Compass .dat files
309  and handle it in the same way as the "DUPLICATE" flag in .svx files.
310
311* cavern: If there's more than one *fix command with coordinates, still
312  actually fix the second and subsequent ones, to avoid triggering bogus errors
313  about unconnected surveys.
314
315* cavern: If there's more than one *fix command with coordinates, report the
316  station name of the previous one, plus the file and line number where it was.
317
318* cavern: Fix handling of the rather contrived case of *fix with no coordinates
319  followed by *solve and then another *fix with no coordinates not to access
320  freed memory.
321
322* dump3d: Report any specified coordinate system.
323
324* doc/3dformat.htm: Update to document how the coordinate system is stored.
325
326* (Microsoft Windows version): Include dump3d in the installer.
327
328* Fix a compiler warning.
329
330* Improve test coverage.
331
332Changes in 1.2.13 (2014-05-15):
333
334* aven: Fix --print option to wait for printing to happen before exiting
335  (previously it would exit right after opening the print dialog, so you
336  couldn't actually print anything out using it).
337
338* aven: Increase the threshold for how close the pointer needs to be to a
339  station from 5 pixels to 7 to try to help touchscreen users.  Reported by
340  Hugh St Lawrence.
341
342* aven: Add "fat finger" mode, toggled by pressing F2, to allow investigating
343  if increasing the minimum pointer to station threshold helps Hugh's problems
344  with using aven on a touch screen device.
345
346* aven: The measuring line was unable to see stations which had just been
347  revealed by toggling surface or underground legs on - this is now fixed.
348
349* aven: Add "hit test grid debug" mode, which shows the hit test grid and how
350  many entries are in each box (toggled by F3).
351
352* aven: Pressing F4 now allows the user to toggle wxWidgets assertion messages
353  off and back on.
354
355* aven: Create the empty hit-test grid data structure lazily, to reduce start
356  up time a little.
357
358* cavern: Improve messages which talk about "tags" and/or "prefixes" in *begin
359  and *end commands to instead talk about "survey names".
360
361* cavern: For ages cavern has warned if you reentered a survey, but this
362  warning was suppressed if it occurred at the same line of the same file as
363  the survey was first entered, but this can only happen if you include the
364  same survey file more than once, which isn't a sensible thing to do for a
365  file with actual survey data in (you might reasonably do it to set up survey
366  grade details or something like that).  The warning is now given in this
367  situation too.
368
369* cavern: After 5 warnings about reentering a survey we give up warning about
370  it, but we used to keep reporting where the survey was originally entered -
371  this secondary diagnostic message is now silenced when the main message is.
372
373* (Microsoft Windows version): Compile C code with optimisation on.
374
375* Add the start of a Russian translation, with messages take from therion.
376
377* Minor translation updates to French.
378
379* Fix compiler warning from GCC.
380
381* Testsuite improvements:
382
383  + Test that "..." anon station works.
384
385  + cavern.tst: Check number of errors returned by all testcases which should
386    fail and give an error count.
387
388  + cavern.tst: Fix to actually fully test everything when builddir != srcdir.
389
390Changes in 1.2.12 (2014-04-14):
391
392* aven: Fix measuring line to show change in altitude rather than altitude
393  itself (accidentally broken by changes in 1.2.11).  Reported by Brian
394  Clipstone.
395
396* aven: Fix printing when built with wxWidgets 3.0.
397
398* aven: Several visual improvements to printouts:
399
400  + Move the numbers below the scale bar down a little so that they don't
401    overlap the scale bar ticks.
402
403  + Set the clipping region after we draw the page border and info box to avoid
404    clipping the border in print preview.
405
406  + Tidy up the appearance of the compass and elevation arrow.
407
408* aven: Fix to build with libav 10.  Reported by Moritz Muehlenhoff in
409  <http://bugs.debian.org/739332>.
410
411* aven: Fix to build with older libav where avcodec_free_frame() isn't
412  available.
413
414* (Linux version) survex.spec: Update spec file used for building RPM packages.
415
416* (Unix version): Add "Keywords:" entry to .desktop files.
417
418* (Unix version): Enable large file support, mostly to support filing systems
419  which return 64 bit inode values, such as CIFS mounts.
420
421* (Microsoft Windows version): Only allow "A-Z" or "a-z" for driver letters,
422  rather than any character which is a letter in the current locale.
423
424* Various translation updates.
425
426Changes in 1.2.11 (2014-01-28):
427
428* aven: Fix wxWidgets assertion when double clicking on an anonymous station.
429  Reported by Kevin Dixon.
430
431* aven: Embed the font data for the first 256 Unicode characters for use in the
432  survey pane into the compiled aven binary to reduce start up overhead.  Any
433  additional characters needed are loaded from a data file only if/when a
434  character >= U+100 is actually needed (as before).
435
436* aven: Fix display of Unicode characters above 256 when there's a character
437  <= 256 earlier in the same string.
438
439* aven: Use the actual width of Unicode characters above 256 rather than
440  assuming they are 16 pixels wide.
441
442* aven: If full screen, don't show the side panel when a new file is opened
443  (e.g. via Ctrl+O).
444
445* aven: Don't give an assertion failure when showing passages for a cave with
446  no vertical extent.  Reported by Jonny Prouty.
447
448* aven: Change terminology in print dialog - say "legend" instead of "info
449  box".
450
451* aven: Add option to show the tilt angle as a percentage gradient.
452
453* aven: Show the units (degrees, grads, or percent) for the tilt and bearing
454  indicators.
455
456* aven: All length units are now translatable.
457
458* aven: Split log_fl_error helper function out of CHECK_GL_ERROR macro, which
459  will reduce code size and also the number of deprecation warnings about
460  gluErrorString on Mac OS X 10.9.
461
462* (Microsoft Windows version): aven: Try to work around redraw issues related
463  to the measuring line by redrawing the whole window, which doesn't seem to be
464  measurably slower.
465
466* cavern: If *units is used to try to set units for LEVEL, PLUMB, or POSITION,
467  give an error rather than quietly ignoring the attempt.
468
469* cad3d: Make cad3d remap control characters and spaces in station names when
470  generating PLT output in the same way aven does.
471
472* Various translation updates (particular thanks to Eric Madelaine and Dennis
473  Baudys), including the start of a Bulgarian translation, with messages taken
474  from Therion and elsewhere.
475
476* (Microsoft Windows version): On Microsoft Windows 2000 and newer, use
477  GetUserDefaultUILanguage() to get the UI language to use.  For older
478  versions, continue to use GetUserDefaultLCID().
479
480* (Microsoft Windows version): The Indonesian translation will now be used
481  automatically when the system language is set to Indonesian.
482
483* (Mac OS X version): Fix to build with wx 3.0.0 on OS X 10.9.  Thanks to David
484  A. Riggs for his work on this.
485
486* (Mac OS X version): Update buildmacosx.sh script to use wx 3.0.0, and add a
487  checksum check for the downloaded wx sources.
488
489* Fix a lot of the compiler warnings when building with clang.
490
491* doc/manual.sgml: Add missing quantities to the list documented as accepted by
492  *units: LEFT, RIGHT, UP/CEILING, DOWN/FLOOR (missing entirely);
493  BACKCOMPASS/BACKBEARING, BACKCLINO/BACKGRADIENT (missing from the main list,
494  mentioned in list of the units that can be set for them); COUNT (missing
495  alternative name for COUNTER); DX/EASTING, DY/NORTHING, DZ/ALTITUDE
496  (incorrectly listed as X, Y, Z).  Reported by Jonny Prouty.
497
498* Test suite: Improve test coverage for cavern.
499
500Changes in 1.2.10 (2014-01-15):
501
502* aven: Fix assertion if two mouse buttons are held down at the same time.
503  If dragging with more than one mouse button held down, releasing one causes
504  another which is still held down to take effect.  Reported by Brian
505  Clipstone.
506
507* aven: If we fail to start the external editor when the user clicks on an
508  error or warning from cavern, show an error box.
509
510* aven: If the survey has a title, add it as a top-level <title> element to
511  exported SVG files.
512
513* aven: Escape '<', '>', and '&' in labels in exported SVG files.
514
515* aven: In GPX export, set the <time> element to the datestamp from the 3d
516  file.
517
518* aven: Don't try to write the title if it isn't set or is empty when exporting
519  GPX files.
520
521* aven: Don't bother looking up the printer page setup info when exporting.
522
523* (Microsoft Windows version): aven: Fix crash on "File->Print" or
524  "File->Export" under Windows XP, reported by Brian Clipstone.
525
526* (Microsoft Windows version): aven: Fix error dialog about an incorrectly
527  encoded filename which could occur if run without being asked to load a file
528  on startup.
529
530* (Microsoft Windows version): aven: Compile with optimisation on.
531
532* img library, aven: Although processed CMAP data files are often referred to
533  as "CMAP .XYZ files", it seems that actually, the extension .XYZ isn't used,
534  rather .SHT (shot variant, produced by CMAP v16 and later), .UNA (unadjusted)
535  and .ADJ (adjusted) extensions are.  Since we've long checked for .XYZ, we
536  continue to do so in case anyone is relying on it, but also check for the
537  other extensions.
538
539* img library: Add new "datestamp_numeric" field to struct img giving the
540  datestamp as a time_t in UTC (or (time_t)-1 if there's no datestamp or we
541  failed to convert it).  For .3d >= v8, this field is reliable.  We attempt to
542  convert date strings in .3d <= v7 and CMAP XYZ files, but may get the
543  timezone wrong.
544
545* img library: Fix my_strcasecmp() to handle top-bit set characters better.
546
547* cavern: Fix NULL pointer dereference when processing Compass DAT file without
548  'SURVEY DATE:'.
549
550* doc/manual.sgml: Update references to Survex 1.1 which should be to 1.2.
551
552* doc/manual.sgml: Note the station length limit Smaps used.
553
554* Fix some compiler warnings if built with glibc's fortify source feature
555  enabled.
556
557Changes in 1.2.9 (2014-01-08):
558
559* Document --3d-version in cavern man page and the manual.
560
561* aven: Fix compilation error in movie export code with recent libavi.
562
563* aven: Fix warning on stderr when export a movie as MPEG.
564
565* img library: In non-hosted mode, don't define GETC and PUTC if they're
566  already defined, to allow easy overriding with getc_unlocked() and
567  putc_unlocked() (which are significantly faster on Linux).
568
569* img library: In non-hosted mode, check that int is at least 32 bits,
570  and if not, use long.  In practice, platforms with 16 bit int are mostly
571  obsolete, but it's not hard to be portable here.
572
573* img library: Add test that img.c and img.h compile in non-hosted mode
574  (regression test for issue fixed in 1.2.8).
575
576* (Microsoft Windows version): aven is now built with wxWidgets 3.0.0.
577
578* Update translations from launchpad and from existing similar messages.
579
580* Fix some compiler warnings.
581
582Changes in 1.2.8 (2013-10-29):
583
584* cavern: Fix handling of anonymous wall stations ('..' by default) to
585  implicitly set the SPLAY leg flag, as was intended.  Reported by Thomas
586  Holder.
587
588* cavern: Tweak .err file output not to lose the space in front of certain
589  statistics when the value gets large.
590
591* cavern: Eliminate redundant progress message when solving simultaneous
592  equations.
593
594* aven: Add a format drop down to the export dialog, and only show fields which
595  are meaningful and supported for the currently selected export format.  The
596  format defaults to that used most recently.  The "Elements" and "View" boxes
597  have been swapped in the print and export dialogs as that layout works much
598  better when the "View" box is hidden.
599
600* aven: Changing checkboxes in the print or export dialog didn't work in 1.2.7
601  - now works again.  Reported by Anthony Day.
602
603* aven: Add GPX export (based on findentrances patch from Olaf Kähler).  In
604  this release the projection which the survey coordinates are in defaults
605  to the BMN M31 grid used in the Totes Gebirge in Austria.  On Unix, you
606  can edit ~/.aven and add a new line setting 'input_projection' to a PROJ
607  projection string.  The ability to specify this projection in a better
608  way is coming soon.
609
610* aven: New export options "Origin in centre" and "Full coordinates" - the
611  latter fixes #10.  GPX and PLT output implicitly force "full coordinates".
612
613* aven: The "Sketch" vector drawing program got renamed to "Skencil" some
614  time ago, so update references.
615
616* aven: Make the Presentation->Play menu item a checkbox, to avoid a warning
617  with wxMSW 2.9.5.  Reported by Brian Clipstone.
618
619* aven: Make right click in an empty presentation mark the current position and
620  open it to edit, instead of crashing.
621
622* aven: Update movie export code to work with latest libav API.  Reported by
623  Sebastian Ramacher.
624
625* aven: Improve reporting of errors during the process of exporting a movie.
626
627* aven: Don't try to close the movie if we aren't producing one.
628
629* aven: Fix assertion failure when double-clicking on the survey with wx2.9.
630
631* aven: Fix to build with wxMSW 2.9.5.
632
633* aven: Fix to build with wx 2.9.5 with wx2.8 compatibility disabled.
634
635* cad3d: The "Sketch" vector drawing program got renamed to "Skencil" some time
636  ago, so add a new --skencil option to specify this output format.  The old
637  name (--sketch) is still recognised for compatibility.
638
639* cad3d: Make --marker-size work for Skencil and SVG output.
640
641* dump3d: Make --show-dates option show dates for XSECT.
642
643* img library:
644
645  + Fix to work once more when used outside of Survex (missing definition of
646    max() macro and a bad call to free() in img_close() for a file opened for
647    reading).
648
649  + Use lround() instead of round(), and make the tests around whether we use
650    the library function or the our fallback implementation saner.
651
652  + Fix // comments in C code for portability to pre-C99 compilers which don't
653    support these as an extension.
654
655  + Can now be compiled as C++ as well as as C.
656
657* (Microsoft Windows version): The installer is now built with a newer version
658  of Innosetup, and includes translations for all the languages which Survex
659  itself has any translations for.
660
661* (Microsoft Windows version): aven is now built with wxWidgets 2.9.5.
662
663* Minor translation updates.
664
665* tests/Makefile.am: Distribute files for "normal_bad" testcase.
666
667Changes in 1.2.7 (2013-07-27):
668
669* Add support for anonymous stations, which are indicated by one, two or three
670  separator characters - with the default separator of '.', that means '.',
671  '..', and '...' are anonymous stations.  Single separator ('.' by default)
672  is an anonymous non-wall point, double separator ('..' by default)
673  is an anoymous wall point at the end of an implicit splay), and triple
674  separator ('...' by default) is an anoymous point (with nothing special about
675  the leg).  A new *alias command allows '-' to be mapped to '..' for
676  compatibility with pocket topo: *alias station - ..
677
678* New version 8 of the 3d format:
679
680  + Supports new flags img_SFLAG_ANON and img_SFLAG_WALL.
681
682  + New explicit file-wide flag for 'this is an extended elevation', rather
683    than modifying the survey title to indicate this.
684
685  + The survey prefix is often unchanged from one leg to the next, so use a
686    spare flag to compactly indicate when there's no label change.
687
688  + The data style of each leg is now stored.
689
690  + The "processed at" time is stored as seconds since 1970 rather than a
691    human-readable string.
692
693  + Since 3d v8 features significant changes to the format, the format
694    documentation for v7 and earlier has been split off into 3dformat-old.htm.
695
696* img library:
697
698  + New station flags img_SFLAG_ANON and img_SFLAG_WALL.
699
700  + Handle .pos files containing unnamed stations - don't suck the next line in
701    as the station name, and set img_SFLAG_ANON for them.
702
703  + Repurpose the long unused fBinary parameter to img_open_write() as a flags
704    parameter, and add img_FFLAG_EXTENDED to specify that this is an extended
705    elevation, in place of appending " (extended)" to the title.  Internally we
706    still append this to the title (and remove it upon reading) when writing
707    3d v7 or earlier, but for the new 3d v8 format, this flag is stored
708    explicitly in the file.
709
710  + img.h: Add comments for the lists of "Leg flags" and "Station flags".
711
712* aven:
713
714  + We now require at least wxWidgets 2.8.0 - it was released over 6 years ago
715    now, and the wx developers consider even 2.8 to be rather long in the
716    tooth.  We stopped testing building with wxWidgets 2.6 some time ago, and
717    formally dropping support for older versions allows a number of workarounds
718    to be removed from the aven source code.  Also, features deprecated in
719    wxWidgets 2.9 are no longer used in our code.
720
721  + Don't run incremental search on every key-press, as on a slow machine the
722    short initial search(es) will take a while but not be useful.  Instead only
723    actually run the search when we're told there are no more key-presses
724    queued up.
725
726  + Implement support for including cross-section information in exported SVG
727    and DXF files (ticket#4).  The DXF export is untested currently.
728
729  + Show splay legs faded by default, with menu options to hide them or show
730    them like other legs.
731
732  + Speed up loading a .3d file with cross-sections by using a map to convert
733    station names to positions.
734
735  + In the cavern log window, don't highlight a file:linenumber if there's no
736    message after it, which avoids highlighting the "Included from" lines
737    wrongly.
738
739  + Fix not to crash when trying to report an error while starting up.
740
741  + (MacOS X version): Change the menu shortcut for "Full Screen Mode" to be
742    the OS X standard shortcut Shift-Command-F (previously we used F11, but
743    that's used by the desktop).
744
745  + Add checks for errors when reading the font file.
746
747  + Remove useless extra quoting when invoking vim to show the location of an
748    error from cavern.
749
750  + Include GL/gl.h before GL/glext.h (needed on Debian wheezy).
751
752  + Use wxValidator to simplify keeping svxPrintDlg member variables and fields
753    in the dialog in sync.
754
755* cavern:
756
757  + Demote errors about invalid dates to warnings, since we've accepted *date
758    for ages without any checks on the value, and so existing datasets
759    probably contain invalid dates and dates in other formats.  (ticket#19)
760
761  + New *alias command allows '-' to be mapped to '..' for compatibility with
762    pocket topo: *alias station - ..
763
764  + We want to warn if there's a clino reading which it would be impossible to
765    have read from the instrument (e.g. on a -90 to 90 degree scale you can't
766    read "93" (it's probably a typo e.g. for "39").  However, the gradient
767    reading from a topofil is typically in the range 0 to 180, with 90 being
768    horizontal.  Really we should allow the valid range to be explicitly
769    specified, but for now we infer it from the zero error - if this is within
770    45 degrees of 90 then we assume the instrument can read between 0 and 180
771    degrees.
772
773  + If the survey isn't all connected, still run survey tree checks and report
774    errors and/or warnings which might suggest typo locations.  Thanks to Kevin
775    Dixon for the report which highlighted this issue.
776
777  + Report a warning if *begin SURVEY has a separator character in SURVEY.
778
779  + Report column numbers as well as line numbers for some cavern errors and
780    warnings.
781
782  + Adjust width of node stats table to fit longest count when there are more
783    than 9999 of a particular order of node.
784
785  + If the argument to *include has an opening double quote but the closing
786    double quote is missing, then skip trying to open the file.
787
788  + Move "Station X referred to just once" warning after non-existent survey
789    check - if both fire, the non-existent survey error is likely to be more
790    relevant.
791
792  + We no longer follow an error for a bad reading in passage data with a bogus
793    "End of line not blank" error, but instead check the remaining readings on
794    the same line.
795
796  + We no longer follow an error about OMIT for a required reading with a bogus
797    "End of line not blank" error.
798
799  + Report an error if the scale factor in *calibrate is zero - it doesn't make
800    sense and probably means someone reversed the arguments to *calibrate.
801
802  + Report the parent include files starting from the outermost, as that's more
803    logical when there are multiple levels involved.
804
805  + If we were expecting a numeric field and instead get something which starts
806    with '+', '-', or '.' but which isn't a number, then fix the error to
807    include that character in the token reported.
808
809  + Simplify handling of quantity lists to only recognise 'DEFAULT' as the
810    first item.
811
812* cad3d: Check for errors from img_rewind() and report them.
813
814* dump3d:
815
816  + Build, install and package dump3d as standard - it's useful for grabbing
817    info from 3d files in scripts.
818
819  + Add --show-dates option.
820
821  + Show only 2 decimal places on coordinates and passage dimensions.
822
823  + Report the data style of legs.
824
825  + Report if the file is an extended elevation.
826
827  + Report img_STOP as STOP rather than CODE_0xffffffff.
828
829* Test suite:
830
831  + cavern.tst: Fix equatenosuchstn testcase (added in 1.2.6) to normalise the
832    expected output so it passes reliably.
833
834  + cavern.tst: Run diffpos <expected> <actual> so the reports of 'Added' and
835    'Deleted' stations upon failure are the more natural way round.
836
837  + Add more testcases, expand some existing testcases, and add expected output
838    for more.
839
840* (Microsoft Windows version): Use wx-config's --cc and --cxx flags to find the
841  appropriate C and C++ compilers to use, and link mingw build statically to
842  avoid needing the libgcc DLL (which newer GCC seems to have by default).
843
844* (Unix version): When determining the character set for command-line tools,
845  check environmental variable LANG after LC_ALL and LC_CTYPE.
846
847* When determining the language, check environmental variable LC_ALL before
848  LC_MESSAGES and LANG (but after SURVEXLANG).
849
850* If we don't find the message file, only give an error if it was specified
851  with SURVEXLANG, since that is an explicit instruction to Survex, whereas
852  LANG, LC_ALL and LC_MESSAGES are essentially system "preferred locale"
853  settings.
854
855* There are a handful of hard-coded English message strings for reporting
856  errors trying loading message files, etc.  These are all now ASCII, as if we
857  fail trying to open a message file, it's more likely the encoding isn't
858  set correctly.
859
860* Prune strings we are no longer using and are probably unlikely to use again
861  into a new file po_codes_dead, so that translators don't get presented with
862  them to translate.
863
864* Merge lots of translation updates.  Most translations are now complete or
865  close to complete.
866
867* Add start of Indonesian translation from Arief Setiadi Wibowo.
868
869* Fix various compiler warnings when building from source.
870
871* Include scripts gdtconvert and gen_img2aven in the source distribution.
872
873Changes in 1.2.6 (2012-02-23):
874
875* (Mac OS X version): Fix so that cavern finds its messages when run by aven.
876
877* (Microsoft Windows version): Include JPEG images for aven in the installer
878  package (ticket#35).
879
880* cavern: If we have a reference to a station in a non-existent survey, give a
881  helpful error rather than saying the station hasn't been exported from the
882  survey.  (Bug reported by Martin Green via email)
883
884* aven: Fix to build with a non-Unicode wxWidgets library.  Patch from Olaf
885  Kahler.
886
887* findentrances: Add findentrances utility from Olaf Kahler which produces a
888  .gpx file with waypoints for entrances.  This needs libproj so is disabled
889  by default for this release - to enable it install the development stuff for
890  libproj and build survex with:
891
892      make FINDENTRANCES=findentrances
893      make install FINDENTRANCES=findentrances
894
895* dump3d: Add support for showing img_ERROR_INFO items.
896
897* doc/3dformat.htm: Merge in some improvements from Mike McCombe.
898
899* Incorporate a French translation from launchpad I'd previously copied the
900  English version of by mistake.  Attempt to correct mistranslation of "survey
901  file".
902
903Changes in 1.2.5 (2012-01-03):
904
905* aven:
906
907  + The survey tree in the left panel is now in sorted order once more.
908
909  + No longer fails with an assertion if used for a long time (we were leaking
910    an OpenGL list each time one had to be regenerated).
911
912  + Now builds with newer FFmpeg library.
913
914  + Draw measuring line in front of the indicators rather than behind them.
915
916  + Loading a new file (or reloading the current one) no longer invalidates
917    the OpenGL lists for the compass and clino, so will be a fraction faster.
918
919* Improve handling of attempts to look up translated messages before the
920  message subsystem is fully initialised (which only happens if there's an
921  error early on).
922
923* Improve the survex(7) man page text, and fix it to be marked as section 7 in
924  the man page source as well as in the filename.
925
926Changes in 1.2.4 (2012-01-01):
927
928* aven:
929
930  + A change in 1.2.3 meant that aven tried to use OpenGL before it was
931    initialised, which doesn't cause problems in some machines, but causes aven
932    to abort on others.  This is now fixed, and there's a check in place to
933    help avoid similar issues in future. (ticket#34)
934
935  + Always use metres or feet for the depth colour key, and chose a consistent
936    precision by looking at the depth range. (ticket#30)
937
938  + Show the depth units below the colour bar rather than after every value.
939
940  + When zooming way in, stay in metres rather than switching to cm.
941
942  + On the scale bar, say “1 mile” rather than “1 miles”.
943
944* Translation updates for Catalan, French and Slovak.
945
946Changes in 1.2.3 (2011-12-31):
947
948* Fix to build with wxWidgets 2.9.2.
949
950* (Mac OS X version):
951
952  + Processing .svx files from aven now works.
953
954  + Remove spurious blank lines from the licence text in "Get Info".
955
956  + Don't create the help menu at all, as it is empty (because the "About"
957    entry goes elsewhere) and sometimes seems to appear in the UI.
958
959  + INSTALL.OSX: Update to reflect current status.
960
961* aven:
962
963  + Fix Y coordinates of surface surveys on printouts.  (Closes #32)
964
965  + Improvements to text plotted on the survey pane:
966
967    - Support plotting Unicode character points > 256 by lazily loading the
968      data for them from the font file and plotting them with a direct call to
969      glBitmap(), which is slower but doesn't require a display list per
970      character.
971
972    - Adjust the spacing from fixed width to putting a one pixel gap either
973      side of each one character (so two between adjacent glyphs).  Mostly this
974      reduces the horizontal width, but it adds a pixel for characters like "m"
975      and two in a few cases.
976
977    - Fix .pixelfont file generation to correctly handle characters wider than
978      8 pixels.
979
980  + Fix expected cross shape so don't always reject using texture mapping to
981    draw crosses.
982
983  + As we read a survey file, eliminate tubes consisting of zero XSECTs as well
984    as those consisting of just one.  Previously we would trip over the empty
985    tube later.  Such tubes can for example be created by extend if a splay shot
986    is the start or end of a tube.
987
988  + Make the green colour used for entrances in the survey tree the same
989    (slightly darker than before) green used for the entrance blobs.
990
991  + Report the version of the library we're actually running with if built
992    against wx >= 2.9.2.  Make it clear that the version reported is the
993    version *built* with for wx < 2.9.2.
994
995* extend:
996
997  + Copy the end markers for passage tubes.
998
999  + Preserve left and right data for tubes (previously they were set to -1.0
1000    which means "no info").
1001
1002* img library: Fix incorrect comment in img.h which claimed that img_XFLAG_END
1003  was no longer used - it certainly is!
1004
1005* Use curly double quotes instead of "`" and "'" to quote filenames, etc in
1006  messages, and curly single right quote instead of straight ASCII apostrophe.
1007  Fall back to using straight ASCII versions if we can't represent them in the
1008  current character set.
1009
1010* Translation updates for Catalan, French, Slovak and Spanish.
1011
1012* Test suite:
1013
1014  + Add test coverage for interleaved diving data.
1015
1016  + Add testcase for diving data with topofil-style distance.
1017
1018Changes in 1.2.2 (2011-10-06):
1019
1020* aven:
1021
1022  + Replace the textured-mapped font drawing with an approach based on
1023    glBitmap.  This doesn't suffer from the character alignment issues which
1024    the textured-mapped fonts had, and is actually significantly faster on some
1025    machines.  The current font used is (mostly) fixed-width, but this isn't an
1026    inherent limitation - it was just the easiest font data to convert to a
1027    usable format.
1028
1029  + Fix assertion failure due to rounding differences on loading certain .3d
1030    files.  (ticket#26)
1031
1032  + Fix assertion failure when turning on 3D passages if they stick out higher
1033    or lower than any station.  (ticket#29)
1034
1035  + Fix grid not to disappear when blobs are turned on and blobs are drawn
1036    using lines.
1037
1038  + If a degree sign isn't available in the character set in use, transliterate
1039    it to 'dg' rather than skipping it.
1040
1041  + Fix message which should have been a degree sign but got lost in the format
1042    change for 1.2.0 and then got reassigned in 1.2.1.  Externally, this means
1043    that bearings in the status bar now have a degree sign after them if they
1044    are in degrees rather than nothing (1.2.0) or "&Hide Compass" (1.2.1).
1045
1046  + Fix print dialog to calculate the scale required for "One page" right
1047    before it calculates how many pages are required, so we don't end up
1048    something other than 1x1 being shown when the user changes settings.
1049
1050  + Update the calculations for picking a scale and for deciding how many
1051    pages are needed to take into account the change in info box height made
1052    in 1.2.1.
1053
1054Changes in 1.2.1 (2011-10-04):
1055
1056* Translation updates for US English.
1057
1058* aven:
1059
1060  + Rename the "depth bar" to "colour key" in documentation, menus, etc since
1061    it now shows colours for dates and errors as well as depths.
1062
1063  + In the colour key for "colour by date", change "No info" to "Undated".
1064
1065  + Remove the dark grey background from the colour key and just put a single
1066    pixel black border around the colours.  This is more in keeping with the
1067    other controls, and means the colours are now on a black background so more
1068    visually similar to the survey legs.
1069
1070  + Move the colour key's "Undated"/"Not in loop" entry down a little to
1071    improve the appearance.  Make each section a pixel taller.
1072
1073  + Allow "Colour by X" to be selected even if there's no data for X or only a
1074    single value of X used (the colour key is much smaller in these cases, and
1075    does still provide some useful information).
1076
1077  + Fix incorrect calculation of depth colouring for survey legs which straddle
1078    a depth band boundary.
1079
1080  + The scale bar, compass, clino, and colour key now all have right click
1081    menus which allow related actions to be performed (especially handy in
1082    full-screen mode).
1083
1084  + Improve the font used on the survey pane - it now contains the '-'
1085    character (so the clino now shows negative angles as negative, and dates
1086    in the colour key are now hyphenated).  Also the spacing and alignment
1087    are a little better, though still not perfect.
1088
1089  + PLT file export now handles spaces and control characters in station names
1090    by escaping them with '%' as in URLs.
1091
1092  + Pressing "Enter" on a station in the tree control now centres the view on
1093    that station.
1094
1095  + The scale bar is now cached in an OpenGL display list since it often gets
1096    redrawn exactly the same - for example, when rotating, panning, etc.
1097
1098  + Pressing "F5" forces all cached OpenGL drawing lists to be invalidated and
1099    then forces a refresh of the survey pane.  This is intended as a debugging
1100    aid - if pressing F5 changes the display at all then there's a missing case
1101    where a list should have been invalidated (please report if you find such
1102    a case as it is a bug).
1103
1104  + We now automatically track which OpenGL display lists need to be
1105    invalidated on window width or height changes.
1106
1107  + Increase scale bar maximum width from 65% of the window width to 75% as it
1108    was in 1.0.x (except that if that would overlap the clino we now reduce
1109    that proportion down until it reaches 50%).  Make the limit of zooming in
1110    the same as in 1.0.x.  (ticket#23)
1111
1112  + (Linux version): Previously wxGTK didn't really handle showing a dialog if
1113    the application was fullscreen (the dialog got opened under the main
1114    window!)  To work around this, aven would switch out of full screen mode
1115    temporarily while showing a dialog.  This case works properly with recent
1116    wxGTK, so disable our workaround with versions we know work.  Also, apply
1117    the workaround only for wxGTK, not everywhere except on Microsoft Windows
1118    as there's no reason to think we need it for other platforms.
1119
1120  + Grey out the "View North" action when we're already viewing North, and
1121    similarly for other compass points.
1122
1123  + (Mac OS X and Microsoft Windows versions): Fix missing newline to OpenGL
1124    info in the "About" dialog.
1125
1126  + Fix to set the correct filename on the root of the survey tree - previously
1127    the filename of the previous file loaded was used!
1128
1129  + The movie export code now works with newer versions of the FFmpeg libraries
1130    as well as still working with older versions.
1131
1132  + Fix mixed up messages - the print dialog now says "View" on the left
1133    subgroup of controls rather than some unrelated message.
1134
1135  + On printouts, combine the "Plan View"/"Elevation" info box field with the
1136    field which gives the bearing and reduce the height on the info box by the
1137    removed field, so it's now 3cm for plans and elevations, as for extended
1138    elevations.  Report the tilt angle for tilted elevations which it seems has
1139    been missing for ages (it's not in recent 1.0.x either).
1140
1141  + Tweak the exact positioning of informational text on printouts to look
1142    nicer and make better use of the available space.
1143
1144  + Add keyboard mnemonics to the "Plan" and "Elevation" buttons in the print
1145    dialog.
1146
1147  + Make the sign of the tilt angle for printouts consistent with the sign
1148    shown by the "clino" in the survey pane.
1149
1150  + In the "Print" dialog, when in plan view disable the "Plan view" button,
1151    and similarly for the "Elevation" button.
1152
1153  + (Microsoft Windows version): Sort out appearance of custom cursors.
1154
1155  + If a label isn't valid UTF-8 or CP1252, fall back to ISO8859-1.
1156
1157  + (Mac OS X version): F11 puts aven into full screen mode, but apparently
1158    you can't get out again easily, so add code to explicitly check for F11
1159    being pressed and toggle full screen.
1160
1161* (Linux version): Fix the RPM .spec file for where man pages now get installed
1162  and package aven.svg and the vim support files.  (Fixes from James Begley)
1163
1164* "make check" now performs several checks on the translation files.
1165
1166* More messages are now available to be translated.
1167
1168* cavern: Fix reporting of ranges of survey coordinates, which was broken by
1169  the message handling changes in 1.2.0.
1170
1171* Fix warning when compiling with GCC.
1172
1173* INSTALL: Mention building wxWidgets with --enable-unicode.  Mention using
1174  sudo for installing on Unix.
1175
1176* In the manual, replace the instructions for building from source with a
1177  pointer to the clearer instructions in INSTALL.
1178
1179* In the manual, make it clear that installing with administrator rights
1180  also applies to newer platforms than XP.
1181
1182* doc/TODO.htm: Update.
1183
1184Changes in 1.2.0 (2011-09-20):
1185
1186* Translation updates for Catalan, French, Romanian, Spanish, Slovak, and US
1187  English.
1188
1189* tests/smoke.tst: aven no longer requires an X display for --help or
1190  --version, so replace skip of this check with a check that this remains the
1191  case.
1192
1193* We now use the standard .po and .pot file formats for storing translations
1194  (rather than the Survex-specific messages.txt format), and then translate
1195  these into Survex's .msg format.
1196
1197* (Unix version): Move survex man page to section 7 (since it isn't documenting
1198  an actual command).
1199
1200* (Unix version): Write each generated man page to a temporary file, then
1201  atomically rename, to avoid leaving an empty or partial man page behind if
1202  docbook-to-man dies (1.1.16 had an empty cad3d.1, and we want to avoid a
1203  recurrence of that).
1204
1205* (Unix version): Default to installing docs into /usr/share/doc/survex rather
1206  than /usr/doc/survex.
1207
1208* aven:
1209
1210  + Fix handling of accented characters in the survey pane.
1211
1212  + Aven icon redrawn in SVG format - it's now a vector image which looks
1213    nicer at larger sizes.
1214
1215  + Explicitly request double-buffering, which seems to be needed for systems
1216    with GLX >= 1.3.
1217
1218  + Fix crash while trying to load certain .3d files.
1219
1220  + Movie export code updated to work with more recent versions of FFmpeg.
1221    Currently this is disabled in Microsoft Windows builds, pending getting the
1222    required libraries set up for building releases.
1223
1224  + Reporting of errors during movie export improved.
1225
1226  + Force playback speed to "x1" during movie export.
1227
1228  + Use stock IDs for buttons where appropriate - such buttons may now be
1229    rendered with icons on some platforms.
1230
1231  + If a label isn't valid UTF-8, treat it as CP1252 (the Microsoft superset of
1232    ISO8859-1).
1233
1234  + (Unix version): Remove special handling for toggling "full screen" on wxGTK
1235    as it's no longer required with modern versions.
1236
1237  + Don't redraw the survey on every mouse movement in the survey pane unless
1238    the measuring line is (or just was) active.  (ticket #17)
1239
1240* cavern:
1241
1242  + Drop "non-fatal" from the report of how many errors there were at the end
1243    of the run - it just confuses users - we won't even get here if there's a
1244    fatal error!
1245
1246  + Add --3d-version option to allow the user to specify the version of the 3d
1247    format to output.  (ticket#21)
1248
1249* img library:
1250
1251  + Make the highest and lowest valid values for img_output_version available
1252    in img.h as IMG_VERSION_MIN and IMG_VERSION_MAX.
1253
1254* (Mac OS X version): Fix buildmacosx.sh script to check where the temporary
1255  volume actually gets mounted.  Fix URL for downloading wxWidgets.
1256
1257Changes in 1.1.16 (2011-05-16):
1258
1259* Translation updates for German, Spanish, Italian, Portuguese, Brazilian
1260  Portuguese, and US English.
1261
1262* Use horizontal ellipses character rather than '...' and right arrow character
1263  rather than '->' where these characters are available.
1264
1265* (Unix version): Link with -lGL, if it exists, to support linking with gold or
1266  GNU ld --as-needed (Debian bug #615781).
1267
1268* img.c:
1269
1270  + Fix code typo for IMG_API_VERSION == 0 case.
1271
1272  + Fix code typo in code used when IMG_HOSTED isn't defined.
1273
1274* doc/TODO.htm: Remove entries which have now been done.
1275
1276* (Microsoft Windows version): aven: We now include all the available
1277  translations for messages from wxWidgets, which means that standard widgets
1278  will appear translated where available even if Survex messages aren't
1279  translated.
1280
1281Changes in 1.1.15 (2010-10-15):
1282
1283* aven:
1284
1285  + In the cavern log window, change the "Rerun" button to "Reprocess" to
1286    follow terminology in manual and elsewhere.  Fixes ticket#15.
1287
1288  + When displaying output from cavern, don't update the window after every
1289    line, but only when we don't have data from cavern pending.  Hopefully
1290    addresses ticket#12.
1291
1292  + If we aren't using GL_POINTS for blobs, draw them using a series of
1293    abutting lines rather than with gluDisk which is faster and gives a
1294    consistent shape.
1295
1296  + Check whether blobs and crosses actually render correctly as points/point
1297    sprites, and if they don't, fall back to drawing them with lines.  The
1298    best method is cached on disk, and rechecked automatically if the graphics
1299    hardware is changed or the drivers upgraded.
1300
1301  + Fix non-USE_FNT case to work again (it's limited to ISO-8859-1 characters
1302    though, so we still enable USE_FNT by default).
1303
1304  + Don't offer "All files" wildcard in presentation save dialog.
1305
1306  + (Microsoft Windows): Handle filenames with non-Latin1 characters in in
1307    more places.
1308
1309  + (Microsoft Windows): Quote filenames with spaces and metacharacters in
1310    when running cavern from aven.  Fixes ticket#11.
1311
1312* editwrap: (Microsoft Windows): Handle filenames with non-Latin1 characters.
1313
1314* diffpos: Handle files with duplicate labels in better - extend generates
1315  duplicate labels when it breaks a loop.
1316
1317* Enable eswap-break testcase now that diffpos handles duplicate station names.
1318
1319* New v7 of .3d format which stores survey dates as number of days since
1320  January 1st 1900, so we now support dates from 1900-2078 (rather than
1321  1970-2037) with a smaller file size.  The img API is now versioned - you
1322  can select the new "version 1" by compiling with -DIMG_API_VERSION=1, which
1323  gives the survey dates in days in days1 and days2 instead of as time_t
1324  values in date1 and date2.  Fixes ticket#14.
1325
1326* Consistently use http://survex.com/ rather than http://www.survex.com/ - the
1327  former has been the canonical name for some time, with www.survex.com just
1328  redirecting to it.
1329
1330* (Unix version): Use unlocked file I/O if available, which can be much faster
1331  in some cases (we don't need the locking as we don't do multithreaded file
1332  I/O).
1333
1334* (Mac version): Fix compilation failure due to clash with Point in Mac OS X
1335  headers.
1336
1337* (Mac version): buildmacosx.sh now works again.
1338
1339* Most tests weren't actually running any testcases (looks like a sh
1340  portability issue).  This is now fixed, and fortunately all tests still pass.
1341
1342* Include the extra .isl translation files for Innosetup in the source archive.
1343
1344Changes in 1.1.14 (2010-07-26):
1345
1346* Restore compatibility with wxWidgets 2.6 (1.1.13 required wxWidgets 2.8).
1347
1348* aven:
1349
1350  + After processing survey data, if there were warnings or errors, add a
1351    "Rerun" button to allow easy reprocessing after fixing problems.  If there
1352    were only warnings, also add an "OK" button to allow moving on to viewing
1353    the processed survey data (fixes ticket#13).
1354
1355  + Optimise updating of the cavern log window (hopefully fixes ticket#12).
1356
1357  + Fix links in cavern log window to link from exactly '<file>:<line>' (and
1358    not the ': ' after), and to make the title for the terminal the
1359    warning/error message.  Avoid false positives by checking that '<line>' is
1360    a number.
1361
1362  + Don't double escape the contents of href and target in links in the cavern
1363    log window.
1364
1365  + Improve handling of the splitter window, fixing behavioural glitches in
1366    various cases.
1367
1368  + Highlight stations matching any current search when a file is loaded.
1369    (ticket#9)
1370
1371  + (Mac version): Fix build issue due to Mac OS X polluting the global
1372    namespace with its own "Point" class.
1373
1374  + (Unix version): The Gnome print dialog has its own preview window so
1375    suppress ours if using the Gnome one.
1376
1377  + (Unix version): Link aven with -lGLU which SuSE Linux needs.
1378
1379  + (Microsoft Windows version): Fix handling of a double-click on the survey
1380    tree when built with wxWidgets >= 2.8.11.
1381
1382* cavern: Report relevant file and line number for three warnings which didn't
1383  give them before.
1384
1385* (Unix and Mac versions): configure: Update the wx-config probing code -
1386  wxmac-config etc aren't present with newer wxWidgets versions so there's no
1387  point looking for them now.
1388
1389* (Mac version): buildmacosx.sh: This script builds a diskimage with Survex in
1390  for easy installation.  Update it to work with the latest Survex versions
1391  (use WX_CONFIG not WXCONFIG; use a Unicode build of wxWidgets; if building a
1392  private wxWidgets, use 2.8.11 not 2.7.0-1).
1393
1394* manual:
1395
1396  + Correctly capitalise "GTK".
1397
1398  + Note that on Linux we only regularly test builds with the GTK+ version
1399    (change taken from 1.0).
1400
1401* Fixed the cad3d man page, which was an empty file in 1.1.13.
1402
1403Changes in 1.1.13 (2010-06-16):
1404
1405* Say "wxWidgets" instead of "wxWindows" consistently.
1406
1407* img.c: Fix small memory leak (filename_opened member).
1408
1409* cad3d, aven: Fix export to SVG when a label contains a '%' character.
1410
1411* aven:
1412
1413  + wxWidgets 2.6.0 or newer is now required.
1414
1415  + A "Unicode" build of wxWidgets is now supported.  An "ANSI" build may still
1416    work but hasn't been tested recently (all packaged versions of wxWidgets
1417    seem to be Unicode now).
1418
1419  + Fix potential uses of uninitialised variables which may have been causing
1420    occasional glitches when loading a file on start-up.
1421
1422  + Improvements to the handling of the font used for plotting labels and other
1423    text on the survey pane:
1424
1425    - Loading the font file is more efficient.
1426
1427    - Character spacing is improved.
1428
1429    - Default font is now anti-aliased.
1430
1431  + "About" dialog:
1432
1433    - Add "Copy" button to copy the system info to the clipboard for easier
1434      bug reporting.
1435
1436    - List OpenGL extensions last, since there are usually lots of them with a
1437      modern gfx card.
1438
1439    - Fix 100% CPU usage while the "About" dialog is open.
1440
1441  + Processing .svx files:
1442
1443    - Passing a .svx file on the command line now works better.
1444
1445    - Put the survey data log window in a splitter in the usual frame rather
1446      than opening a separate frame for it.
1447
1448    - Auto-scroll the log window until we've reported a warning or error.
1449
1450    - Fix small memory leak.
1451
1452  + The presentation filename now defaults to using the basename of the
1453    currently loaded dataset, but we always prompt before we first save with
1454    such a name.
1455
1456  + Reduce memory usage when saving a screenshot.
1457
1458  + Allow "Toggle Fullscreen" to work even if no survey is loaded now that we
1459    persist the window size (and maximised or fullscreen state) between
1460    invocations.
1461
1462  + Fix reporting of OpenGL errors.
1463
1464  + Fix glitches when tilting while looking East.
1465
1466  + Added Portuguese and Slovak translations of wxWidgets messages.
1467
1468* Documentation:
1469
1470  + Rationalise manual formats - replace PostScript with PDF and drop RTF.
1471
1472  + Drop the "alternative manual formats" self-extracting zip file - people
1473    will generally just want one of the formats, so downloading several
1474    together isn't very useful.
1475
1476  + 3dformat.htm: Update for v6 format (thanks to Mike McCombe).
1477
1478  + GPL.htm: Replace HTML version of licence with a link to the version on
1479    the FSF website.
1480
1481  + ChngeLog.htm: Stop generating an HTML version of the ChangeLog - it's too
1482    low level to be of interest to non-developers, and developers can look at
1483    the source code.
1484
1485* (Unix version): configure: New preferred name for specifying wx-config script
1486  is WX_CONFIG.  WXCONFIG still supported for compatibility.
1487
1488* (Linux version): Source RPM package dropped as you can just build an RPM
1489  package from the source tarball.
1490
1491* (Microsoft Windows version): The installer is now created with a newer
1492  version of InnoSetup, which gives a 10% smaller download.
1493
1494Changes in 1.1.12 (2007-02-07):
1495
1496* aven:
1497
1498  + Remember the window size or maximised/fullscreen state between invocations.
1499
1500  + Add options dialog to "Export" similar to the one for "Print".
1501
1502  + The "number of pages required" in the print dialog now updates when you
1503    change what is to be shown (underground legs/surface legs/station
1504    names/crosses).
1505
1506Changes in 1.1.11 (2006-11-25):
1507
1508* Updated Czech, Spanish, and Slovak translations.
1509
1510* (MacOS X version): Assorted OS X specific tweaks and fixes.
1511
1512* aven:
1513
1514  + Pick a smaller and clearer font for labels.
1515
1516  + Fix character spacing.
1517
1518  + Tweak display of bearing and elevation angles to look nicer with
1519    proportional fonts.
1520
1521  + Use the title from the 3d (or plt, etc) file for the window title
1522    rather than the filename.
1523
1524  + Show distances to 2 decimal places rather than the nearest integer.
1525
1526  + Only consider underground legs when calculating the depth bands and
1527    depth colouring.
1528
1529  + Add "Colour by Error".
1530
1531  + Add entry for "white" in date and error keys.
1532
1533  + When setting the view to a single point, don't change the scale.
1534
1535  + If reloading the same file, don't change the view
1536
1537  + Fix filetypes selector in open dialog.
1538
1539  + Fix the charset we use for aven in certain cases.
1540
1541  + Call msg_init before using msg_lang or it won't ever be set!
1542
1543  + Pass wx the full language code to initialise the C library locale.
1544
1545  + Fix bug in generating prefix tree view which could lead to a bogus
1546    leading dot on some survey names (bug probably introduced in 1.1.10).
1547
1548  + "New Presentation" now ensures that the side panel is open
1549
1550  + Fix updating of cached opengl lists when the view is reset to the
1551    default.
1552
1553* Ignore LANG if it starts with a digit to avoid problems with bogus value for
1554  LANG which AutoCAD installation seems to set on MS Windows.
1555
1556* (Unix version): configure: Allow SGMLTOOLS and DOCBOOK_TO_MAN to be
1557  specified.  Either/both can be set to ":".
1558
1559* dump3d: Report unknown (to dump3d) codes returned by img.
1560
1561* img library: Flag all stations as underground in the old "ASCII" .3d format.
1562
1563Changes in 1.1.10 (2006-07-14):
1564
1565* aven: Clicking on a survey name in the survey tree now highlights it in
1566  the map view.  Double-clicking zooms the view to show the clicked survey
1567  highlighted.  Clicking the root clears the highlighting and double-clicking
1568  the root restores the default view.  To expand/collapse a branch, click
1569  on the "[+]" or "[-]" icon to the left of the survey name.
1570
1571* aven: The measuring line can now measure to anywhere in plan or elevation
1572  view (not just to a station!)  In plan view the horizontal distance and
1573  bearing are shown, while in elevation view the vertical distance is shown.
1574
1575* aven: Moving the mouse over a station in the survey view now highlights
1576  that station in the survey tree (though it may not be visible if the
1577  survey(s) it is in aren't expanded).
1578
1579* aven: Clicking on a station to centre the view now moves the mouse pointer
1580  to the new location of the station (except on Mac OS X where this isn't
1581  allowed).
1582
1583* aven: Fix which presentation toolbar buttons are shown as depressed.
1584
1585* Fix infinite loop reading 3d files with LRUD data (bug introduced in 1.1.9).
1586
1587* vim files are now installed with the correct paths (bug introduced in 1.1.9).
1588
1589Changes in 1.1.9 (2006-07-04):
1590
1591* (Unix version): Install desktop files for aven and svxedit contributed to the
1592  Ubuntu package by Phil Bull, and corresponding pixmaps.
1593
1594* Fix img to filter out cross-sections which don't match the subsurvey (if
1595  specified).  The API now returns img_XSECT_END to mark the end of a
1596  passage rather than setting a flag on the last img_XSECT of the passage.
1597
1598* Enhance integration with the vim editor - this can now colour .err files, run
1599  cavern from vim and parse error output, and run aven from vim.  Tweak the
1600  existing vim mode for .svx files to fix a few minor bugs and add support for
1601  the new "*data passage" style.
1602
1603* aven: fix drawing of the "blob" end of the measuring line on graphics cards
1604  which can't draw large enough blobs for us.
1605
1606* aven: sort out confusion about what encoding everything is in which means
1607  that the distance measured by the measuring line actually gets displayed
1608  and also fixes problems with empty menu items in non-English locales in
1609  some cases.
1610
1611* aven: redraw grey background after a menu is closed over the aven window
1612  with no survey loaded.
1613
1614* aven: fix bug which caused printing to crash (introduced in 1.1.8).
1615
1616* aven: avoid crash on some machines when opening "About" dialog before having
1617  loaded a survey.
1618
1619* aven: Translate "Plan" and "Elevation" buttons in print view dialog.
1620
1621* (Unix version): aven: Fix character set handling of cavern output.
1622
1623* cavern: Report an error if a cross-section is specified for a station which
1624  doesn't exist.
1625
1626* Updated French and Italian translations.
1627
1628* (Unix version): aven: Fix "Can't open message file `en_US' using path
1629  `${prefix}/share/survex'" error.
1630
1631* Fix bug in 3d file reading on 64 bit platforms when used in STANDALONE mode
1632  (doesn't affect Survex itself, but other applications which use img.c should
1633  update their copy).
1634
1635* (Unix version): Add checks that wxWidgets is a non-unicode version (wx 2.6
1636  and later are caught by configure, whereas older wx versions are caught when
1637  trying to compile).
1638
1639Changes in 1.1.8 (2006.06.30):
1640
1641* Drop support for building with wxWidgets versions prior to 2.4.0
1642  (which was released on 2003-01-07).
1643
1644* aven: Printing through aven now uses settings from the "[aven]" section
1645  of print.ini, and support for hierarchical sections (using "like=")
1646  has been disabled.
1647
1648* aven: Change mouse actions to be compatible with those in Survex 1.0.
1649  The mousewheel now zooms in/out (it doesn't do anything in 1.0) and
1650  left drag is now smart about not rotating and zooming at the same
1651  time.
1652
1653* aven: Highlighting stations now happens as you type, and pressing
1654  "Enter" or clicking the "Find" button now pans and zooms to show the
1655  highlighted stations.
1656
1657* aven: Left-clicking away from a station now cancels measuring line.
1658
1659* aven: Setting view to North, South, East, or West is now animated like
1660  the tilt from plan to elevation.
1661
1662* aven: Fix presentation saving to also write "." for decimal points and
1663  presentation loading to accept either "." or ",".
1664
1665* (Unix version): aven: Add text for all toolbar items so that aven
1666  will work with the Gnome desktop preference for displaying toolbars as
1667  icons with text or just text (wxWidgets needs fixing first though).
1668
1669* (Unix version): aven: Remove the ability to detach the menu bar (yell
1670  if you actually used it and I'll restore it!)
1671
1672* aven: Add "all survey files" option to the "open file" dialog.
1673
1674* (MS Windows version): aven: Fix cursor keys to pan survey.
1675
1676* (MS Windows version): Built with wxWidgets 2.6.3 instead of 2.6.2.
1677
1678* (MS Windows version): Fix installer to work on Windows 2000 or XP if
1679  run by an unprivileged user.
1680
1681* (MS Windows version): Upgrade to the latest version of InnoSetup (the
1682  installer builder we use) and include new installer translations for
1683  UK English, Spanish, Brazilian Portuguese, Italian, Romanian, and Slovak.
1684
1685* (MS Windows version): aven: Include Catalan and Brazilian Portuguese
1686  translations of messages for wxWidgets (the GUI library we use).
1687
1688* aven: Disable "Highlight exported points" if there aren't any.
1689
1690* Updates to French translation from Michel Bovey.  Also updates to German,
1691  Italian, Catalan, Spanish, and Romanian translations.
1692
1693* (Unix version): test suite: fix smoke test to pass even without X running
1694  (it was meant to but the code had a bug).
1695
1696* aven: Check if OpenGL is available and exit cleanly with a helpful error
1697  if it isn't.
1698
1699* (Unix version): aven: Fix --help and --version to work without a working
1700  X display (provided it's built with wxWidgets 2.5.1 or newer).
1701
1702* aven: Automatically select the presentation tab of the notebook when the user
1703  selects "New Presentation" or "Open Presentation".
1704
1705* aven: Fix "Delete" in the presentation list to not get passed on (and so not
1706  reset to default view as well).
1707
1708* aven: Fix Ctrl+Insert in the presentation list not to segfault if the list is
1709  empty.
1710
1711* aven: Fix Cursor Up and Down in the presentation list to move the highlight
1712  up and down instead of being passed on and moving the survey.
1713
1714* aven: Improve SVG output compatibility.  Tested with Mozilla Firefox 1.5,
1715  Adobe's SVG browser plugin, Gimp 2.2.8, Gqview 2.0.0, Opera 8.5,
1716  Safari 2.0.3, and InkScape 0.42.
1717
1718* aven: Put a 5mm border around exported SVG files to allow for station markers
1719  and non-zero width lines.
1720
1721* aven: Fix crash when exporting as SVG or Sketch if labels or surface data
1722  was turned on.
1723
1724* aven: Actually close the file we're exporting which fixes problems with it
1725  not always being fully written.
1726
1727Changes in 1.1.7 (2005.10.18):
1728
1729* cavern: Add validity checking for dates in *date commands (with feature
1730  test in testsuite).  A date entered as just "year" or "year.month" now
1731  becomes a date range for the relevant period (previously it became a single
1732  date near the middle of that period).
1733
1734* extend: Fixed 2 uninitialised flags (should fix erratic behaviour on
1735  with MS Windows).
1736
1737* extend: Default output name for a file called input.3d is now input_extend.3d
1738  rather than just extend.3d (which was annoying if you wanted to extend
1739  several surveys in the same directory).
1740
1741* aven: OpenGL 2.0 always includes support for point sprites so rework
1742  our check for them to include that knowledge.
1743
1744* aven: Regenerate depth bar if user switches to/from metric units.
1745
1746* aven: Don't clear the "there" mark just because the mouse pointer has
1747  moved off a station.
1748
1749* aven: When processing a .svx file, put the resultant .3d file in the
1750  same directory (since that's where we then try to load it from).
1751
1752* aven: Fix labelling of date colouring on 32 bit platforms.
1753
1754* aven: If "colour by date" is on and we load a survey with no date info
1755  (or all surveyed on the same date) then set "colour by none".
1756
1757* aven: Make the error dialog modal and remove a signal handler once it
1758  has fired to prevent endless (or seemingly endless) cascades of error
1759  dialogs.
1760
1761* aven: Enforce a minimum object volume diameter of 1m to avoid problems
1762  if a survey file with only one station in is loaded.
1763
1764* aven: Fix problems with indicators disappearing when we're drawing
1765  blobs and/or crosses the slow (but always supported) way.  (Problem
1766  introduced in 1.1.6).
1767
1768* (Unix version): aven: Really stop setting extra toolbar margin when using
1769  GTK2.0.  The attempt to fix this in 1.1.3 failed because __WXGTK12__ is
1770  set for GTK+ 1.2 or *any later release* so is true for GTK+ 2.0 too!
1771
1772* (Unix version): aven: Add details of which of wxGTK, wxMotif, and wxX11
1773  we've been compiled with, and which GTK+/Motif version where appropriate.
1774
1775* (Unix version): Fixed build on Fedora Core 3.
1776
1777* documentation: Updates to 3d file format specification from Mike McCombe.
1778
1779Changes in 1.1.6 (2005.10.10):
1780
1781* (MS Windows version): Distribution is about a third smaller than 1.1.5
1782  (mostly because mingwm10.dll is no longer required).
1783
1784* aven: If aven is asked to load a .svx, .dat, or .mak file, run cavern on
1785  it, showing cavern's output in a window (with errors and warnings clickable
1786  to load the offending file into an editor), and then loading the resulting
1787  3d file.
1788
1789* aven: Added "Colour by Date" option.
1790
1791* aven: Disable "Colour by Depth" option if there's no elevation variation.
1792
1793* aven: Don't crash if trying to load a survey with no elevation variation.
1794  Instead turn off depth colouring.
1795
1796* aven: Export as HPGL added.
1797
1798* aven: Improved update of mouse coordinates and measuring line (thanks to
1799  Martin Green).
1800
1801* aven: Show the coordinates of either the mouse pointer or the nearest
1802  survey station to it (if there is one near enough).  Showing both was
1803  confusing and meant the status bar overflowed on smaller displays.
1804
1805* aven: When printing an extended elevation, don't show bearing and elevation.
1806
1807* aven: Don't lock "flat" surveys which aren't extended elevations - a
1808  flat survey with LRUD data isn't flat any more!
1809
1810* aven: When we have to draw blobs and crosses the slow way (because the
1811  graphics hardware doesn't support the fast way), draw them so that they
1812  should appear at the correct depth into the 3D scene instead of on top
1813  of everything else.
1814
1815* aven: Make "play presentation backwards" icon green to match the other
1816  presentation icons.
1817
1818* (MS Windows version): aven: Mouse clicks on the survey view now set the
1819  keyboard focus there.
1820
1821* (MS Windows version): aven: Fix first redraw of a newly loaded survey.
1822
1823* (MS Windows version): aven: Fix redrawing of measuring line.
1824
1825* cavern: Store dates for img_XSECT.
1826
1827* cavern: Fixed small one-off memory leak if you specify -o more than once.
1828
1829* (Unix version): Check environmental variable LC_MESSAGES when deciding what
1830  language to use for messages.
1831
1832* (MS Windows version): "Print" on a 3d file now prints through aven rather
1833  than the separate printer driver (Unix has done this for some time).
1834
1835* Removed old printer drivers.
1836
1837* img library: When creating a 3d file, ignore img_XSECT if we've been asked
1838  to write a file format version which doesn't support it.
1839
1840Changes in 1.1.5 (2005.09.20):
1841
1842* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).
1843
1844* aven: Make blobs round like they are in Survex 1.0.
1845
1846* aven: If the graphics drivers don't support drawing blobs using OpenGL
1847  point markers, fall back to drawing filled circles.
1848
1849* aven: If the graphics drivers support it, draw crosses as texture mapped
1850  OpenGL point markers which is much faster.
1851
1852* aven: Cross size increased to match Survex 1.0.
1853
1854* aven: We must update which blobs are displayed if display of surface or
1855  underground legs is toggled.
1856
1857* cavern: Fix handling of a *solve followed by survey data, none of which is
1858  attached to the previous data.
1859
1860* cavern: Fixed "No survey data" error when a *solve is followed by another
1861  *solve (or the implicit solve at the end of processing) with no data between
1862  them.
1863
1864Changes in 1.1.4 (2005.09.19):
1865
1866* aven: Added Aven's icon to the "About" dialog.
1867
1868* aven: Use localised character for the decimal point (e.g. "," in most
1869  continental European countries).
1870
1871* aven: Previously the survey tree would get focus and then take keypresses
1872  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
1873  operate on the cave, and transfer the input focus across when we do.
1874
1875* aven: Make pressing "Return" in the tree control expand/collapse a subtree.
1876
1877* aven: Speed up intialisation by delaying creation of OpenGL lists until
1878  they're needed.
1879
1880* aven: Added Mark Shinwell's bounding box with shadow of the survey.
1881
1882* aven: Disable the "Tubes" button/menu item when there's no LRUD data.
1883
1884* aven: Reworded "Restore Default Settings" as "Restore Default View".
1885
1886* (Unix version): aven: Set sensible default margins for printing and preserve
1887  any margin values the user specifies between runs (previously margins
1888  defaulted to 0 each time aven was run).
1889
1890* Documentation: Document *DATA PASSAGE in the manual.
1891
1892Changes in 1.1.3 (2005.09.07):
1893
1894* (Microsoft Windows version): Fixed build problems.
1895
1896* cavern: Allow OMIT character (-) for left/right/up/down.
1897
1898* aven: Remove an unnecessary menu separator.
1899
1900* aven: Fix "Find" and "Hide" toolbar buttons to work with GTK2.0.
1901
1902* aven: Make the tooltip for "Hide" show the number of found stations.
1903
1904* aven: If * or ? is used in a glob-style pattern, force a non-substring match.
1905
1906* aven: Enable "New Presentation" when there's a 3d file loaded, rather than
1907  when there's a presentation loaded.
1908
1909* aven: Make entrances green in side panel tree list to match green blobs used
1910  in cave view.
1911
1912* aven: Don't show surface labels if we're not showing surface data, etc.
1913
1914* aven: Merge "Start Rotation" and "Stop Rotation" into "Toggle Rotation" and
1915  make "Space" the key for this.  Keep Return working "Stop Rotation" so
1916  existing users are happy, but don't advertise it.
1917
1918* aven: Normalise filename by adding any extension used, and use the normalised
1919  filename for file history and window title.
1920
1921* (Unix version): aven: Stop setting extra toolbar margin when using GTK2.0
1922  as the toolbar buttons already have a sensible margin - the extra margin is
1923  only needed with GTK1.2.
1924
1925* aven: Fix handling of plumb legs in tube model.
1926
1927* aven: Fixed swapped L and R in tube model.
1928
1929* extend: Preserve UD cross-section information in extended elevation.
1930
1931* extend: Add new messages for John Pybus' enhancements.
1932
1933Changes in 1.1.2 (never formally released):
1934
1935* Added support for LRUD data in .svx files, in .3d files, and aven can
1936  now load and display it on screen and on printouts.  The ability to "fake"
1937  LRUD data in aven is gone for now but will reappear in some form later.
1938
1939* cavern: Removed support for writing Chasm's 3dx format.  We're going to
1940  fold any desirable missing chasm functionality into aven.
1941
1942* aven: Rearranged mouse actions as discussed on the mailing list.  Added
1943  cursors for each different mouse action to help the user learn what each
1944  does.  Also added cursors for the "compass" and "clino" as well as the
1945  scalebar to suggest to the user that they can be dragged to change the view.
1946
1947* (Unix version): aven: Don't segfault if LANG isn't a known language.
1948
1949* tests/smoketest.tst: If X windows is running, check that we can run aven
1950  with --help and --version.
1951
1952* tests/cavern.tst: Fixed cavern.tst to warn if it is skipping a test because
1953  no results are listed for it.  This revealed that there was a "newline" test
1954  which should have been called "badnewline", and was a broken testcase too!
1955  Fixed all these problems.
1956
1957* cavern: Applied Simeon Warner's patch for handling backcompass, backclino,
1958  and omitted forward compass/clino readings in Compass DAT files.  Added
1959  a feature test for this to the testsuite.
1960
1961* It no longer makes sense to have an option not to build aven or to build aven
1962  without OpenGL so remove old machinery for this from configure and the
1963  sources.
1964
1965* (Unix version): configure: Check if "-lXxf86vm" is needed.
1966
1967* configure: Better output for strcasecmp test.
1968
1969* aven: Fix crosses to work much better.  Not a total fix - their position
1970  in the Z buffer isn't correct and they're rather slow to plot.
1971
1972* aven: Don't regenerate the hittest grid every time the mouse moves while
1973  animating, which solves the mysterious pausing effect (thanks go to Martin
1974  Green for spotting this!)  Also clear all the status bar coordinates when
1975  animating.
1976
1977* aven: Sort out clashing menu shortcuts in some languages.
1978
1979* aven: Fixed compilation problem on x86_64
1980
1981* SPUD: Pruned out stuff which has been done or which is not actually relevant
1982  to this branch.
1983
1984* Merge various changes from 1.0 branch:
1985
1986  + aven: Port over "printing from aven" functionality.
1987
1988  + aven: Port over "export as" functionality,
1989
1990  + Add David Loeffler's vim mode for .svx files.
1991
1992* aven: Fix check for whether a label is behind us in perspective view.
1993
1994* aven: Don't use an opengl list for drawing the indicators - we typically make
1995  a new list each time we plot them anyway.
1996
1997* Remove lingering traces of support for RISC OS and pre-386 MSDOS
1998
1999* aven: Set icon on non-Windows platforms too.  This means that with
2000  WindowMaker on Unix you get an icon on the AppIcon by default.
2001
2002* configure: Update wxWindows checks to handle newer wx versions.
2003
2004* Make all maintainer perl scripts "use bytes;" to avoid utf-8 double encoding
2005  problems.  They also all require Perl 5.8 now (hopefully this isn't an issue
2006  for anyone building from CVS).
2007
2008* acinclude.m4: Quote macro name for fix autotools warning.
2009
2010* Documentation: "tilt up" is "'" not ",".
2011
2012* aven: Add support for mousewheels (to tilt the cave).
2013
2014* aven: Fixed twisted transitions to and from pitches in certain cases.
2015
2016* aven: Pick a sensible initial window size when the user's desktop is spread
2017  over more than one monitor (works best with wx2.5 or newer, but try to do
2018  better with wx2.4 or earlier as well).
2019
2020* aven: Initialise GfxCore slightly later to avoid visual glitch from notebook
2021  contents being visible before any survey is loaded.
2022
2023* aven: Allow a coloured texture to be used
2024
2025* aven: Don't initialise until we have data (to the user, this means the window
2026  is default colour (grey for most systems) not black until a survey is
2027  loaded).
2028
2029* aven: Fixed weird "shadowed" icons.
2030
2031Changes in 1.1.1 (2004-10-06):
2032
2033* (Microsoft Windows version): aven: Hopefully fix loading a survey file at
2034  startup.
2035
2036* aven: Delay loading the bitmap for the "About" dialog until it is first
2037  needed.  We want start up to be as quick as possible.
2038
2039Changes between 1.0.32 and 1.1.0 (never formally released):
2040
2041* NOTE: Survex 1.1.X releases are development snapshots made available for
2042  the purposes of allowing wider testing and getting more user feedback.  Once
2043  the code has stabilised the version number will be raised to 1.2.0.
2044
2045* aven: Now uses OpenGL for 3d rendering - you may need to install drivers if
2046  you're using Windows 95 - these can be obtained from:
2047  http://download.microsoft.com/download/win95upg/info/1/W95/EN-US/Opengl95.exe
2048
2049* aven: Solid passages - passage dimensions are currently inferred from
2050  the leg length (pretty effective as you can measure longer legs in
2051  larger passages).  Use of real LRUD data coming soon...
2052
2053* aven: Depth colouring is now continuously varying.
2054
2055* aven: Colour by depth can now be turned off (and there's the start of a
2056  framework for properly implementing colour by date, error, etc).
2057
2058* aven: Find stations moved onto the toolbar and now uses a simple wildcarded
2059  match (? matches any character, * matches any number of characters).
2060
2061* aven: We now use the status bar for coordinates, distances, etc to make
2062  better use of screen space.
2063
2064* aven: Full screen mode (F11).
2065
2066* aven: Perspective view.
2067
2068* aven: Context sensitive cursor shape - needs more work.
2069
2070* aven: Mouse actions changed (hopefully they're now more natural, but
2071  you may find the change disorientating - feedback wanted on this).
2072
2073* aven: Added "presentations" which allow you to set up fly-through paths
2074  and load/save/run them.
2075
2076* aven: A presentation can be exported as a movie file.
2077
2078* aven: Added Save screenshot facility.
2079
2080* aven: Depth fogging option.
2081
2082* aven: Added Smooth Lines option.
2083
2084* aven: Added Textured Walls option.
2085
2086* aven: If a survey has surface legs but no underground legs, default to
2087  showing the surface legs.
2088
2089* cavern: Dates given to *date are now stored in the 3d file.
