Wed Aug 04 03:27:22 GMT 2010  Olly Betts <olly@survex.com>

        * src/img.c: Fix cast in get16() to be to short not long.

Wed Aug 04 02:32:16 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc,src/cavernlog.h: "Rerun" -> "Reprocess" to follow
          terminology in manual, etc.  Fixes ticket#15.

Wed Jul 28 17:06:49 GMT 2010  Olly Betts <olly@survex.com>

        * tests/: Most tests weren't actually running and testcases (looks like
          a sh portability issue).  Fixed, and fortunately all tests still
          pass.

Mon Jul 26 12:30:43 GMT 2010  Olly Betts <olly@survex.com>

        * doc/manual.sgml: Fix typo "of" -> "on".

Mon Jul 26 11:59:59 GMT 2010  Olly Betts <olly@survex.com>

        * NEWS,configure.in: Update for 1.1.14.

Mon Jul 26 11:53:01 GMT 2010  Olly Betts <olly@survex.com>

        * lib/messages.txt,src/: Remove things we no longer need now we've
          dropped support for RISC OS and DOS.

Mon Jul 26 11:19:40 GMT 2010  Olly Betts <olly@survex.com>

        * src/cmdline.c: Remove reference to MSDOS.

Mon Jul 26 10:23:07 GMT 2010  Olly Betts <olly@survex.com>

        * src/: Strip out "Far" and "Huge" which we no longer need now that
          DOS memory models are no longer relevant.

Mon Jul 26 09:57:37 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in: No need for AC_PROG_MAKE_SET when using automake.

Mon Jul 26 09:48:10 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in,src/useful.h: On little-endian architectures, make
          get16() and get32() inline functions, rather than macros which use 
          a global variable.

Mon Jul 26 09:31:14 GMT 2010  Olly Betts <olly@survex.com>

        * src/useful.c: Remove commented out code.

Mon Jul 26 09:19:19 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in,src/img.c,src/useful.c,src/useful.h: Use AC_TYPE_INT16_T
          and AC_TYPE_INT32_T instead of home-brew equivalents.

Mon Jul 26 08:40:43 GMT 2010  Olly Betts <olly@survex.com>

        * src/listpos.c: In "Station X referred to just once, with an explicit
          prefix - typo?" warning, give file and linenumber where the *equate
          occurred.

Mon Jul 26 08:37:46 GMT 2010  Olly Betts <olly@survex.com>

        * src/readval.c: Fix comment typo.

Mon Jul 26 08:29:41 GMT 2010  Olly Betts <olly@survex.com>

        * src/listpos.c: In "Station X referred to by *entrance or *export but
          never used" warning, give file and linenumber where the *entrance or
          *export occurred.

Mon Jul 26 07:44:26 GMT 2010  Olly Betts <olly@survex.com>

        * src/aventreectrl.cc: Fix double-click handling for survey tree on
          wxMSW >= 2.8.11.

Mon Jul 26 07:25:59 GMT 2010  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Stop passing wxNO_FULL_REPAINT_ON_RESIZE as it is 0
          on all versions of wxWidgets we support (i.e. 2.6 and later).

Mon Jul 26 07:21:35 GMT 2010  Olly Betts <olly@survex.com>

        * INSTALL,src/: Restore compatibility with wxWidgets 2.6.

Mon Jul 26 06:29:03 GMT 2010  Olly Betts <olly@survex.com>

        * src/netskel.c: In "Unused fixed point" warning, give file and
          linenumber where the "*fix" occurred.

Mon Jul 26 06:24:35 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Fix highlighting of links in CavernLog window to
          highlight just <file>:<line> (and not the ': ' after), and to make
          the title for the terminal the warning/error message.  Make the
          checking stricter by checking that the linenumber is a number, to
          avoid false positives.

Mon Jul 26 04:48:12 GMT 2010  Olly Betts <olly@survex.com>

        * Revert this change, as it appears wxMotif does support wxGLCanvas:
        * doc/manual.sgml: wxMotif apparently doesn't support wxGLCanvas, which
          is required by Aven in 1.1.x, so remove mention of Motif from manual.

Mon Jul 26 03:24:38 GMT 2010  Olly Betts <olly@survex.com>

        * src/: Add "Rerun" and "OK" buttons to the CavernLog window (as
          appropriate).  (Addition of "OK" button fixes ticket#13).  Fix up
          handling of splitter window to fix poor handling of various cases.

Sun Jul 25 15:32:42 GMT 2010  Olly Betts <olly@survex.com>

        * src/mainfrm.cc,src/mainfrm.h: Clean up code which sorts out loading
          a file (and processing it first if necessary).

Sun Jul 25 07:20:05 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.h: Fix filename in comment at top.

Sun Jul 25 07:17:20 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Don't double escape the contents of href and target
          in links in the log.

Sun Jul 25 06:32:24 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Remove commented out calls to set the input
          encoding of the HTML parser - we now always escape non-ASCII
          characters as HTML entities.

Fri Jul 23 14:15:25 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.h: Improve doc comment for process() method.

Fri Jul 23 12:38:43 GMT 2010  Olly Betts <olly@survex.com>

        * src/printwx.cc,src/printwx.h: Don't compile in the preview code when
          we disable the preview feature.

Fri Jul 23 12:15:31 GMT 2010  Olly Betts <olly@survex.com>

        * src/printwx.cc: The Gnome print dialog has its own preview window
          so suppress ours if using the Gnome one.

Fri Jul 23 11:21:52 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in: Update the wx-config probing code - wxmac-config etc
          aren't present with newer wxWidgets versions.

Fri Jul 23 05:55:37 GMT 2010  Olly Betts <olly@survex.com>

        * buildmacosx.sh: Update to use WX_CONFIG not WXCONFIG.  Update to
          use a Unicode build.  If building a private wx, use wx 2.8.11 not
          2.7.0-1 (and don't replace carbon-glcanvas.cpp with our own version).

Sat Jul 10 12:15:23 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Set the select timeout before calling wxYield()
          when waiting for output from cavern to 0.1s instead of 0.00001s to
          avoid yielding excessively on slower machines where this is likely
          to really slow things down.  Call Scroll() only once per line in
          the case where we are updating the scrollbar position.  Call
          Update() instead of wxYield() after each line, since that's enough
          to get the window updated.  Remove unused assignment "ch = left;"
          at end of loop.

Fri Jul 09 14:42:47 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in: Link aven with -lGLU which SuSE Linux needs.

Fri Jul 09 14:31:39 GMT 2010  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Highlight stations matching any current search when a
          file is loaded.  (ticket#9)

Thu Jul 01 12:20:58 GMT 2010  Olly Betts <olly@survex.com>

        * survex.iss.in: Clean up comments from over-enthusiastic search and
          replace which modified comments as well as code.

Thu Jul 01 10:15:06 GMT 2010  Olly Betts <olly@survex.com>

        * src/gfxcore.h: Work around Mac OS X polluting the global namespace
          with a "Point" class.

Thu Jul 01 10:10:45 GMT 2010  Olly Betts <olly@survex.com>

        * src/Makefile.am: Remove FIXME which has already been resolved.

Fri Jun 18 11:04:35 GMT 2010  Olly Betts <olly@survex.com>

        * doc/manual.sgml: wxMotif apparently doesn't support wxGLCanvas, which
          is required by Aven in 1.1.x, so remove mention of Motif from manual.

Fri Jun 18 03:03:55 GMT 2010  Olly Betts <olly@survex.com>

        * doc/manual.sgml,src/aventreectrl.cc,src/gfxcore.cc,src/mainfrm.h:
          Correctly capitalise "GTK".

Fri Jun 18 02:58:06 GMT 2010  Olly Betts <olly@survex.com>

        * doc/manual.sgml: Note that on Linux we only regularly test builds
          with the GTK+ version (change taken from 1.0).

Wed Jun 16 04:44:26 GMT 2010  Olly Betts <olly@survex.com>

        * doc/Makefile.am: Use stampfile to stop unwanted rebuilds of the HTML
          version of the manual.

Wed Jun 16 02:59:48 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in: Only ask for core, gl, and html wx libs to avoid
          linking to a load of others we don't use.

Tue Jun 15 17:01:41 GMT 2010  Olly Betts <olly@survex.com>

        * INSTALL: Update.

Tue Jun 15 16:53:28 GMT 2010  Olly Betts <olly@survex.com>

        * src/aven.cc: Fix to work with wxWidgets 2.6 too.

Tue Jun 15 15:38:49 GMT 2010  Olly Betts <olly@survex.com>

        * lib/survex-aven.desktop,lib/survex-svxedit.desktop: Merge in .desktop
          file updates from 1.0.39.1-4 Debian package.

Tue Jun 15 14:40:04 GMT 2010  Olly Betts <olly@survex.com>

        * doc/Makefile.am: Fix lingering references to @DOCS_OTHER@.

Tue Jun 15 14:32:55 GMT 2010  Olly Betts <olly@survex.com>

        * NEWS: Update from ChangeLog.

Tue Jun 15 14:09:29 GMT 2010  Olly Betts <olly@survex.com>

        * Makefile.am,configure.in,doc/Makefile.am,make_release: Scrap the
          "alternative manual formats" zip file - people will generally just
          want one of them, so downloading several together isn't very useful.
          Replace PostScript version of manual with a PDF version (more
          compact and more people will have software to read PDF).  Don't
          generate RTF format by default as PDF is more useful if you want
          a formatted version to print.

Tue Jun 15 13:36:30 GMT 2010  Olly Betts <olly@survex.com>

        * doc/manual.sgml: Merge the "Contributing" section into the "Mailing
          List" section.

Tue Jun 15 12:57:13 GMT 2010  Olly Betts <olly@survex.com>

        * Makefile.am,make_release: Just produce a zip file with the
          alternative manual formats - a self-extracting .exe is harder to
          use on other platforms, and most people have a zip file extractor
          installed.

Tue Jun 15 12:36:13 GMT 2010  Olly Betts <olly@survex.com>

        * survex.spec.in: Update survex.com URLs to drop "www.".  Update
          wxGTK dependency to >= 2.6.0.  Reenable "BuildRequires:" as
          the issue with building the package on Debian is no longer
          relevant.

Tue Jun 15 12:35:19 GMT 2010  Olly Betts <olly@survex.com>

        * doc/manual.sgml: Update (C) years.  "MacOS X" -> "Mac OS X".

Tue Jun 15 12:13:42 GMT 2010  Olly Betts <olly@survex.com>

        * doc/manual.sgml: Remove out of date postal addresses - we can
          probably safely assume people have email these days.  Direct
          people to the mailing list since they are likely to get a
          quicker response rather than mailing individuals.  Remove
          mention of a paper mailing list.  Remove mention of sending
          us a floppy (!) or blank CDR to get a version as I can't recall
          the last time I gave someone a copy on physical media.

Tue Jun 15 11:22:56 GMT 2010  Olly Betts <olly@survex.com>

        * Makefile.am,make_release: I can't persuade rpmbuild to work sanely,
          and people can just as easily build binary RPMs from the source
          tarball as from the srpm, so just remove the rpm target from the
          makefile and code which uses it from make_release - it's less to
          have to maintain too.

Tue Jun 15 10:59:12 GMT 2010  Olly Betts <olly@survex.com>

        * make_release: Use "set -e" rather than checking the exit codes of
          commands.  -t no longer disables targets - set mk to do that.

Tue Jun 15 09:41:11 GMT 2010  Olly Betts <olly@survex.com>

        * make_release: Fix defaulting of list of things to do.

Tue Jun 15 09:12:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/gdtconvert: Add "Generated" comment to output file.

Tue Jun 15 09:10:02 GMT 2010  Olly Betts <olly@survex.com>

        * src/gdtconvert: Add GPL license boilerplate.

Tue Jun 15 08:53:28 GMT 2010  Olly Betts <olly@survex.com>

        * src/gettexttomsg.pl,src/wx.h: Add GPL boilerplate to files which were
          missing it.

Tue Jun 15 08:46:28 GMT 2010  Olly Betts <olly@survex.com>

        * src/: Update FSF address in licence notices.

Tue Jun 15 08:06:09 GMT 2010  Olly Betts <olly@survex.com>

        * src/guicontrol.cc: Allow "Toggle Fullscreen" to work even if no
          survey is loaded now that we persist the window size between
          invocations.

Tue Jun 15 08:03:53 GMT 2010  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: Use GL_BLEND rather than GL_ALPHA to work better with
          anti-aliased TXF files.

Tue Jun 15 07:59:09 GMT 2010  Olly Betts <olly@survex.com>

        * src/fnt.cc: Use font size from txf file rather than trying to
          calculate it from the texture fragment sizes.

Tue Jun 15 07:48:13 GMT 2010  Olly Betts <olly@survex.com>

        * lib/Makefile.am,lib/TexFont.h,lib/gentexfont.c: Generate aven.txf with
          afm2txf.pl instead of gentexfont because gentexfont's licence doesn't
          allow distribution of modified versions.

Tue Jun 15 07:43:48 GMT 2010  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Add support for -o option to specify output .txf
          file.

Tue Jun 15 07:10:16 GMT 2010  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Sanitise $FONT to ensure it doesn't contain a '/'.
          Remove the temporary .ppm file at the end.

Tue Jun 15 06:13:30 GMT 2010  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Fix alignment of characters, backported from PLIB
          SVN.

Tue Jun 15 05:05:05 GMT 2010  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Quote $FONT when passing to external commands.

Tue Jun 15 04:24:33 GMT 2010  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Change character 96 from "grave" to "quoteleft".

Tue Jun 15 04:22:59 GMT 2010  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Extend to cover ISO-8859-1, not just ASCII.

Tue Jun 15 04:08:34 GMT 2010  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Clean up trailing whitespace.

Tue Jun 15 04:02:40 GMT 2010  Olly Betts <olly@survex.com>

        * lib/afm2txf.pl: Add GPL script for creating txf files.

Mon Jun 14 06:33:11 GMT 2010  Olly Betts <olly@survex.com>

        * lib/splash.png: Remove now unused graphical splash screen (it has
          hardcoded (C) details, which wasn't a good approach).

Mon Jun 14 05:20:44 GMT 2010  Olly Betts <olly@survex.com>

        * src/fnt.cc: Handle the left bearing and character width correctly.

Mon Jun 14 04:44:22 GMT 2010  Olly Betts <olly@survex.com>

        * src/fnt.cc: Change back to not using GL_COLOR_INDEX, but with still
          being able to set the font texture from a byte array.

Mon Jun 14 04:23:22 GMT 2010  Olly Betts <olly@survex.com>

        * src/fnt.h,src/gla-gl.cc: Pass the length of the string to
          fntTexFont::puts() rather than recalculating it inside the
          method.

Sun Jun 13 12:57:08 GMT 2010  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Fix switching to and from the CavernLogWindow pane
          to use wxSplitterWindow::ReplaceWindow() which fixes various issues
          with sizing and resizing of the panes.

Sun Jun 13 12:23:23 GMT 2010  Olly Betts <olly@survex.com>

        * src/: Add wmsg_cfgpth() which caches the result of msg_cfgpth() as
          a wxString.

Sun Jun 13 06:57:07 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc,src/gla-gl.cc,src/mainfrm.cc: wxString::fn_str() on
          wxmsw returns a wide string, which doesn't work with fopen(), etc, so
          call char_str() instead for now.

Sun Jun 13 05:41:30 GMT 2010  Olly Betts <olly@survex.com>

        * src/printwx.cc: Use wxString::FromAscii() for the units on the scale
          bar which we know to be ASCII.  No need to use msgPerm() for a
          message we assign to a wxString.

Sun Jun 13 04:44:30 GMT 2010  Olly Betts <olly@survex.com>

        * src/mainfrm.cc,src/printwx.cc: Use wxFileName::SplitPath() instead of
          baseleaf_from_fnm().

Sun Jun 13 00:57:11 GMT 2010  Olly Betts <olly@survex.com>

        * src/export.cc,src/gfxcore.cc: wxString::fn_str() on wxmsw returns
          a wide string, which doesn't work with fopen(), etc, so call
          char_str() instead for now.

Sat Jun 12 15:07:54 GMT 2010  Olly Betts <olly@survex.com>

        * src/aven.cc: We can rely on our message catalog being UTF-8 so use
          wxString::FromUTF8() instead of wxConvUTF8.

Sat Jun 12 14:26:32 GMT 2010  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Use wxString::FromAscii() to convert date to
          wxString.

Sun Jun 06 09:36:06 GMT 2010  Olly Betts <olly@survex.com>

        * src/Makefile.am: Use wx-config's --rescomp option to get the command
          and options needed to turn .rc files into object files.

Fri Jun 04 15:32:27 GMT 2010  Olly Betts <olly@survex.com>

        * survex.iss.in: Specify "LZMANumFastBytes=273" which shaves a small
          amount of the installer size.  Specify "DisableWelcomePage=yes"
          which is apparently in line with what other modern installers do.

Fri Jun 04 14:32:04 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in,make_release,make_release.in: We no longer need VERSION
          in make_release, so no need to generate it from configure.

Fri Jun 04 14:00:58 GMT 2010  Olly Betts <olly@survex.com>

        * Makefile.am,xvfb-run: We no longer need an X display to run ISCC
          under Wine, so just run wine directly and removed version of
          Debian's xvfb-run script.
        * make_release.in: Pass variables to configure on the command line
          rather than in the enviornment.  Running "make distcheck" no longer
          fails extend.tst, so remove comment about that.  Use case rather
          than expr to check what we've been asked to build.  Update to use
          unicode wx-config script for wxmsw.  The wxmsw build spews warnings
          about aliasing issues, so turn on -fno-strict-aliasing to avoid any
          potential bugs from that.  Enable -Werror for the wxmsw build.
        * Makefile.am: Update list of wxstd.mo files we package for wxmsw
          (add pt and sk) and where we copy them from.  Copy the unofficial
          InnoSetup i18n files (.isl) from lib.

Fri Jun 04 13:40:35 GMT 2010  Olly Betts <olly@survex.com>

        * doc/HACKING.htm: Update InnoSetup info.

Fri Jun 04 13:07:01 GMT 2010  Olly Betts <olly@survex.com>

        * survex.iss.in: Update for InnoSetup 5.3.9.
        * lib/English_GB.isl,lib/Romanian-7-5.1.11.isl: Check in the unofficial
          i18n files for InnoSetup which we use.

Fri Jun 04 13:05:18 GMT 2010  Olly Betts <olly@survex.com>

        * src/Makefile.am: Update path to wx RC file.

Fri Jun 04 12:44:39 GMT 2010  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Explicitly construct temporary wxString() which
          is needed to avoid overload ambiguity under __WXMSW__.

Fri Jun 04 12:41:59 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Add missing wxT() to string and character
          constants only used in __WXMSW__ build.

Fri Jun 04 12:19:18 GMT 2010  Olly Betts <olly@survex.com>

        * src/aven.cc: wxWidgets now has a Slovak translation, so remove the
          kludge to substitute Czech if Slovak isn't found.

Fri Jun 04 05:08:14 GMT 2010  Olly Betts <olly@survex.com>

        * src/aboutdlg.cc: Fix character constant to be a string constant when
          building under WXMSW.

Thu Jun 03 13:53:57 GMT 2010  Olly Betts <olly@survex.com>

        * NEWS: Update from ChangeLog for 1.1.13.

Thu Jun 03 12:25:14 GMT 2010  Olly Betts <olly@survex.com>

        * Makefile.am,configure.in,debian/Makefile.am,debian/changelog: Remove
          .deb building machinery from upstream Makefile.

Thu Jun 03 12:14:16 GMT 2010  Olly Betts <olly@survex.com>

        * make_release.in: Remove ancient workaround for getting wine to work.
          Remove .deb building machinery.  Reenable distcheck to see if the
          problem with extend.tst has gone away.  Update mingw cross-building
          machinery.

Wed Jun 02 13:30:28 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in,doc/GPL.htm,doc/index.htm.in: Remove HTML version of GPL
          - just link to the FSF's page.

Wed Jun 02 13:26:55 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in,make_release,make_release.in,update-debcl.pl: Use dch to
          update debian/changelog.

Wed Jun 02 12:59:33 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in,doc/Makefile.am,doc/cl2html.pl,doc/index.htm.in: Stop
          generating an HTML version of the ChangeLog - it's too low level to
          be of interest to non-developers, and developers can look at the
          source code.

Wed Jun 02 09:38:25 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Whitespace tweaks.

Wed Jun 02 09:28:37 GMT 2010  Olly Betts <olly@survex.com>

        * src/aboutdlg.cc,src/aboutdlg.h: Use standard button for "Copy" in
          About dialog.  Change "OK" button to "Close" since nothing is being
          confirmed by clicking it.  Call "Flush()" in wxTheClipboard to try
          to make the copied text persist after aven is closed, though this
          seems to currently do nothing on wxGTK at least.

Tue May 18 12:59:00 GMT 2010  Olly Betts <olly@survex.com>

        * doc/HACKING.htm: Note jadetex needed.
          Note autoconf 2.64 works well.

Tue May 18 02:06:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/fnt.cc: Remove now superfluous ().

Mon May 17 14:33:00 GMT 2010  Olly Betts <olly@survex.com>

        * debian/Makefile.am: Update EXTRA_DIST

Mon May 17 05:38:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/cavernlog.cc: Fix small memory leak

Mon May 17 05:33:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/img.c: Don't leak filename_opened member.

Mon May 17 05:13:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Initialise all GfxCore's member variables so we
          don't use them uninitialised.

Mon May 17 05:11:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/gfxcore.h: Declare constants with enum rather than #define so
          they automatically get allocated unique values, and so they show up
          in the debugger.

Mon May 17 02:39:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/fnt.cc: Make the map array static const

Mon May 17 02:30:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/fnt.cc: Set the font texture with GL_COLOR_INDEX so we can
          use a "byte format" font file without any translation, while a
          "bitmap format" font file needs a temporary array half the size.

Mon May 17 00:56:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/gfxcore.cc: Initialise 3 flags when we load a survey to avoid
          using them potentially uninitialised.

Sun May 16 14:39:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Fix cavern log window to behave if passed a .svx
          file on the command line.

Sun May 16 14:27:00 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in: Update copyright years.

Sun May 16 14:23:00 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in, src/aboutdlg.cc, src/aboutdlg.h, src/aven.cc,
          src/aven.h, src/avenprcore.cc, src/avenprcore.h,
          src/cavernlog.cc, src/cavernlog.h, src/export.cc, src/fnt.h,
          src/gfxcore.cc, src/gla-gl.cc, src/gla.h, src/guicontrol.cc,
          src/log.cc, src/mainfrm.cc, src/mainfrm.h, src/namecmp.h,
          src/printwx.cc, src/printwx.h:
          + Fix to build with a "unicode" build of wx.
          + Add "Copy" button to the About dialog to copy the system info
            to the clipboard.
          + List OpenGL extensions last, since there are usually lots of
            them with a modern gfx card.
          + When processing survey data, auto-scroll the log window until
            we've reported a warning or error.
          + Put the survey data log window in a splitter in the standard
            frame rather than having a separate frame for it.

Sat Apr 17 12:13:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/aboutdlg.cc: Add case for "GTK+ >= 2.6".

Sat Apr 17 12:12:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/aboutdlg.cc: Build string using preprocessor string
          concatenation rather than runtime appending, where possible.

Sat Apr 17 12:00:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/aboutdlg.cc: Update (C) date.

Sat Apr 17 11:59:00 GMT 2010  Olly Betts <olly@survex.com>

        * src/aboutdlg.cc, src/aboutdlg.h: Use a wxTimer instead of idle
          events to avoid spinning on the CPU.

Sat Apr 17 11:41:00 GMT 2010  Olly Betts <olly@survex.com>

        * configure.in: New preferred env var for wx-config script is
          WX_CONFIG.  WXCONFIG still supported for compatibility.

Tue Jul 28 08:16:00 GMT 2009  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: The presentation filename now defaults to using
          the basename of the currently loaded dataset, but we always prompt
          before we first save with such a name.

Tue Jul 28 04:37:00 GMT 2009  Olly Betts <olly@survex.com>

        * configure.in: Add comment to explain why we call wx-config twice.

Tue Jul 28 04:36:00 GMT 2009  Olly Betts <olly@survex.com>

        * src/datain.c: Use fputs(m, f) instead of fprintf(f, m) in case m
          contains '%' (m comes from the messages file, so this isn't
          exploitable by sending someone a "bad" .svx or .3d file).

Mon Jul 27 03:29:00 GMT 2009  Olly Betts <olly@survex.com>

        * src/mainfrm.cc: Fix to open rather than save when doing "open
          presentation" with wxmotif.

Thu Mar 05 01:45:00 GMT 2009  Olly Betts <olly@survex.com>

        * doc/3dformat.htm: Document that this is version 6 and when we
          started to use it.

Mon Dec 15 10:34:00 GMT 2008  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: When saving a screenshot, perform the vertical
          flip of the image data in-place rather than using wxImage::Mirror()
          which creates a whole new wxImage object.

Fri Dec 12 11:12:00 GMT 2008  Olly Betts <olly@survex.com>

        * src/cad3d.c, src/export.cc: Fix export to SVG when a label
          contains a '%' character.

Fri Dec 12 06:30:00 GMT 2008  Olly Betts <olly@survex.com>

        * configure.in: Add AM_PROG_CC_C_O which newer autoreconf warns is
          needed.

Fri Dec 12 06:28:00 GMT 2008  Olly Betts <olly@survex.com>

        * configure.in: Remove AC_SUBST of CRLIB and CROBJX which are no
          longer set or used.

Fri Dec 12 06:03:00 GMT 2008  Olly Betts <olly@survex.com>

        * NEWS, buildmacosx.sh, configure.in, desc-aven.txt, doc/TODO.htm,
          doc/manual.sgml, doc/survex.ent, lib/messages.txt,
          src/aboutdlg.cc, src/aven.cc, src/aven.h, src/gfxcore.cc,
          src/mainfrm.cc, src/printwx.cc, src/printwx.h, src/wx.h: Say
          "wxWidgets" instead of "wxWindows" consistently.
          Require wxWidgets 2.6.0 or newer - 2.4 is really old now.

Mon Mar 31 01:53:00 GMT 2008  Olly Betts <olly@survex.com>

        * doc/3dformat.htm: Update for v6 format from Mike McCombe

Fri Sep 07 18:29:00 GMT 2007  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: Calling glGetError() resets the error state, so we
          need to store the value in a variable rather than calling it twice!

Fri Sep 07 13:54:00 GMT 2007  Olly Betts <olly@survex.com>

        * src/gla-gl.cc: Add missing CHECK_GL_ERROR() calls and correct
          some which had the wrong descriptions.
          Use GL_POINT_SPRITE and GL_COORD_REPLACE instead of
          GL_POINT_SPRITE_ARB and GL_COORD_REPLACE_ARB.  They have the same
          numeric values, so the shorter (now official) names are better.

Fri Sep 07 13:31:00 GMT 2007  Olly Betts <olly@survex.com>

        * src/Makefile.am, src/gfxcore.cc, src/gfxcore.h, src/gla-gl.cc,
          src/gla.h, src/matrix4.cc, src/matrix4.h, src/quaternion.cc,
          src/quaternion.h: Just set the pan and tilt directly as OpenGL
          rotations rather than messing around setting up and then decoding a
          quaternion.  This fixes some glitches when tilting while looking
          east, and eliminates 2 source files and 2 headers!

Sat Feb 10 13:56:00 GMT 2007  Olly Betts <olly@survex.com>

        * NEWS, configure.in, src/aven.cc, src/wx.h:
          (Unix version): aven: Fix display of degree symbol in status bar and
          messages with accented characters in.
          (Mac OS X version): Require at least wxWidgets 2.5.1.

Sat Feb 10 13:46:00 GMT 2007  Olly Betts <olly@survex.com>

        * src/message.c: Test S_ISREG since that's what we use here

Sat Feb 10 13:37:00 GMT 2007  Olly Betts <olly@survex.com>

        * src/message.c: Always use utf-8 for aven on unix
