PENTA: the whole file is freakin penta...
Same as gl_bumpmap.c but geforce3&4 optimized
These routines require 4 texture units an some need nvidia shaders
Most lights reqire 2 passes this way
1 diffuse
2 specular
If a light has a cubemap filter it requires 3 passes
1 attenuation
2 diffuse
3 specular
