...like chris, I don't really know what's going on here, beyond some  
driver implementations returning huge numbers for the shader  
objects...however, I do know that currently we've implemented the ARB  
GLSL extensions, and that this has been "internalized" into GL 2.0,  
with some api changes...many of these changes aren't just function  
names, but also return values are changed from GLhandleARB* to  
GLuint, so maybe this ID problem will disappear once I finish a GL  
2.0 native implementation of the GLSL objects?
