[ptx] beta version available for pano12.dll with improved optimizer

[Rik Littlefield]

I forgot to mention that the modified sources are posted at the same 
site.  diff -r -w reports about 700 lines of mods, almost all in 
adjust.c and optimizer.c .  I get a good view of the changes by firing 
up a side-by-side file comparison viewer between my sources and the ones 
I got from cvs.  (My personal favorite is Beyond Compare, 
http://www.scootersoftware.com/ ).

I will let Jim and Bruno speak to how they like to maintain the cvs 
repository.
