PENTA: the whole file is freakin penta...
Same as gl_bumpmap.c but Radeon 8500+ optimized
These routines require 6 texture units, vertex shader and pixel shader
This could be further optimized for Radeon 9700 (specular exponent for
example), but would need better documentation and extension.
All lights not require only 1 pass:
1 diffuse + specular with optional light filter
