Survex 1.1.5 development snapshot uploaded

[Olly Betts]

I've tracked down the problem with 1.1.4 crashing during startup on MS
Windows.  I've also fixed and improved several other things since 1.1.4
so I think another snapshot is called for.

You can download 1.1.5 from:

http://www.survex.com/software/1.1.5/

Please note that this is a test build of the development version.
Things should mostly work, but you're a lot more likely to encounter
problems than with the stable 1.0.X versions.  I'd certainly not
recommend installing this as your only survex version and going on
expedition...

But please download it, try it out, and report any problems.  I'd also
appreciate success stories.

Again, not all reported issues are fixed yet.  I've flagged reports I've
not yet dealt with in my mail reader, so there's no need to re-report a
problem as "still not fixed" unless it's listed as fixed below (on the
other hand it's useful to know if something ISN'T listed but IS fixed!)

Changes in 1.1.5:

* (MS Windows version): aven: Fixed crash on start-up (introduced in 1.1.4).

* aven: Make blobs round like they are in Survex 1.0.

* aven: If the graphics drivers don't support drawing blobs using OpenGL
  point markers, fall back to drawing filled circles.

* aven: If the graphics drivers support it, draw crosses as texture mapped
  OpenGL point markers which is much faster.
 
* aven: Cross size increased to match Survex 1.0.

* aven: We must update which blobs are displayed if display of surface or
  underground legs is toggled.

* cavern: Fix handling of a *solve followed by survey data, none of which is
  attached to the previous data.

* cavern: Fixed "No survey data" error when a *solve is followed by another
  *solve (or the implicit solve at the end of processing) with no data between
  them.

Changes in 1.1.4:

* aven: Added Aven's icon to the "About" dialog.

* aven: Use localised character for the decimal point (e.g. "," in most
  continental European countries).

* aven: Previously the survey tree would get focus and then take keypresses
  (e.g. "P", "L", "Delete").  Now we pass most keypresses across so they
  operate on the cave, and transfer the input focus across when we do.

* aven: Make pressing "Return" in the tree control expand/collapse a subtree.

* aven: Speed up intialisation by delaying creation of OpenGL lists until
  they're needed.

* aven: Added Mark Shinwell's bounding box with shadow of the survey.

* aven: Disable the "Tubes" button/menu item when there's no LRUD data.

* aven: Reworded "Restore Default Settings" as "Restore Default View".

* (Unix version): aven: Set sensible default margins for printing and preserve
  any margin values the user specifies between runs (previously margins
  defaulted to 0 each time aven was run).

* Documentation: Document *DATA PASSAGE in the manual.

Cheers,
