PENTA: the whole file is freakin penta...
Same as gl_bumpmap.c but Matrox Parhelia optimized
These routines require 4 texture units and EXT_vertex_shader and
MTX_fragment shader extensions.
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
