Survex 1.0.2 released

[Olly Betts]

I've just uploaded Survex 1.0.2.  This fixes a few bugs, and adds some new
features.

Download from:

I took a look at Carto's .plt file reading routine, and it ignores most of the
information in the plot file.  So I've added very rudimentary support for
producing .plt files to cad3d - the files produced contain only what Carto
looks for, and I very much doubt Compass can read them.  If you're using Carto,
give it a try and let me know how well it works.

I've also added support for reading .plt files - you can now load these with
any Survex program which expects a .3d file (aven, caverot, cad3d, etc).
Ironically, Survex can't currently read the .plt files it produces...

Changes between 1.0.1 and 1.0.2:

* printdm/printpcl/printwin: take notice of font_size_labels setting in
  print.ini etc.

* cavern: Topofil can now be used with DIVING and CYLPOLAR styles; TOPOFIL
  style is now synonymous with NORMAL.

* cavern: *INFER EQUATES and *DATA TOPOFIL now work together correctly.

* cavern: *FIX with 3 standard deviations but no covariances now works.

* (Mac OS X version): command line programs now build.  We're working on Aven.

* Updates to the Catalan and Spanish translations.

* xcaverot: documented environmental variables XCAVEROT_INDICATOR_RADIUS and
  XCAVEROT_FONTNAME.

* cad3d: added --plt option to produce crude approximation to Compass .plt
  files - should be good enough for reading into Carto.

* img library enhanced to allow Compass .plt files to be read as if they were
  .3d files.

Cheers,
Olly
