Survex 1.1.1 test version uploaded

[Mike McCombe]

For what it's worth, I find the Aven's new user interface a huge improvement 
on the old one. I always seemed to accidentally rotate when I wanted to 
zoom...

Also good to see Olly pushing back on the "computing arrogance" that 
sometimes creeps into postings on this list!

I thought I'd see if 1.1.1 fixed arithmetic precision problem I reported a 
few weeks ago.

*fix test.1 0,0,0

3 4 10 270 0
4 1 10 0 0

5 6 10 0 0
6 7 10 270 0
7 8 7 180 0
8 5 10 90 0
*end test


A quick look at the result with 3dtopos suggests you've fixed it but loading 
the 3d file into Aven gives a dialog box containing

"Assertion failed! ... File: gfxcore.cc... line: 1953... Expression: how_far 
 >= 0..." The process then locks up and has to be removed with the Windows 
Task Manager. (It sits in an unresponsive loop grabbing increasing amounts 
of memory).

Is there a spec for the new 3d format?

All the best,
Mike
