[FreeWRL] FreeWRL 1.20.1

[John A. S. <ale...@cr...>]

Dear FreeWRLians;

I have put 1.20.1 out on source. changes below. I had to make a  
release because of some
MIDI on OSX changes that had to be fixed for my work.

Hopefully DanielT will be able to produce some binary distros for  
Linux boxes in the next
couple of days.

Anyone able to help him out??

Here is the CHANGELOG:

For 1.20.1
         - Midi nodes - pan values were reversed. Fixed.

         - polyrep collision with high NavigationInfo speed not  
working 100%; some changes
           made, but code still needs debugging.

         - "Sensitive" nature of sensitive nodes would flow up the  
scenegraph too far, now
           code verifies that sensitive nodes are indeed registered;  
branches above sensitive
           nodes ignored.

         - Collision equations for collision with Polyreps improved by  
having a quick check
           to reduce testing on all triangles of distant shapes.

         - Frustum culling was not working on OSX computers -  
differences in OpenGL headers
           between Linux and OSX; a #ifdef AQUA added to differentiate.

         - EAI/SAI changes for VRML parser - keep DEFines around  
between calls of cParse.

         - possible threading issue fixed whereby a script can be  
called in Routing before parsing has
           initialized it.

Thanks;
