Replace the numerous switch-statements to derive GL_COMBINE post-scale
state with a function. This function sets the bits correctly. Did some trivial refactoring on some of the GL_COMBINE code. First pass at replacing classic texture environments with GL_COMBINE. This is controlled by the EXPERIMENTAL_COMBINE_MODE define.
