Screenshot of bug

The shadow mapping demo from norsetto doesn't render correctly with r600g, none
of the objects are textured and the shadows are missing. Rendering on llvmpipe
seems to be correct.

The demo requires a simple change for the shaders to compile:

Rendering of the demo has improved, the only thing missing now is the shadow.
