LibGL+LibSoftGPU: Implement rasterization position

Browse source 
Implements support for `glRasterPos` and updating the raster position's
window coordinates through `glBitmap`. The input for `glRasterPos` is
an object position that needs to go through the same vertex
transformations as our regular triangles.
