Yeah, I wouldn't want to remove the reliance on extensions.  I can
think of about 3 ways to determine file type, and I still like using
extensions the best.  I probably wouldn't be complaining about it at
all if shaders just had standard extensions.  You could make shaders a
special case inside OSG, but this is probably a bad idea.  For now I
figured the best first step (and maybe last step) is to route them
through the glsl loader.
