Sub-picometre values in depth legend labels

[Duncan Collis]

This quirk has been in Aven since whenever. I suspect that most people, like me, have just ignored it since it doesn't impede use of the software; it's merely a cosmetic defect.

As an example, the depth scale on the survey I'm currently looking at is labelled starting at -1.14e-10mm. This is plainly spurious... we try hard to maintain a reasonable degree of survey precision, but I think that the nearest metre should usually be acceptable on Aven's depth scale!

Fixed in trunk r3922.

Thanks for prodding me to actually sort this out - I've noticed it myself, and meant to sort it out.
