The problem appears to be that we expect the GL_ARB_fragment_program
extension in order to enable the new volume rendering code. Otherwise
you get the backwards compatability code. I am not certain what the
Quadro4 900 XGL card is, I'll have to look it up. I do note that it
shows GL_EXT_Cg_shader is supported so perhaps that subsumes
GL_ARB_fragment_program and we just need to check for that as well.

PS: Would you please double check that the /usr/include/GL/glext.h file
is the one for the NVIDIA driver?
