LibGL+LibGPU+LibSoftGPU: Implement matrix stack per texture unit

Browse source 
Each texture unit now has its own texture transformation matrix stack.
Introduce a new texture unit configuration that is synced when changed.
Because we're no longer passing a silly `Vector` when drawing each
primitive, this results in a slightly improved frames per second :^)
