393 6067 d 20 h jab /branches/wireframe-experiments/ Creating a branch of GEL for certain wireframe experiments  
/branches/wireframe-experiments
392 6077 d 19 h jab /trunk/ Many mostly minor changes. The QuatTrackball and GLViewController had
some questionable code that I improved. Fixed a bug in the loader.

Note that exceptions were removed from Geometry/Polygonize.cpp since it did not play nice with visual studio 2005. An improved solution is needed so that the program does not just abort.

369 6109 d 18 h jab /trunk/src/GLGraphics/ The SOIL - simple opengl image library is in the public domain. I added it to
GEL because it is much simpler to use and more compact than DevIL.
By including it in the actual GEL distribution, we also lower the number
of external dependencies by 1 while slightly increasing compilation time.
