LibGL+LibSoftGPU: Implement fixed pipeline support for GL_COMBINE

Browse source 
`GL_COMBINE` is basically a fixed function calculator to perform simple
arithmetics on configurable fragment sources. This patch implements a
number of texture env parameters with support for the RGBA internal
format.
