Subject: [PATCH] Fix directional lights for AMD

Some AMD drivers do not like triangles for point sprites, which
breaks directional lights.  This works around this by allowing
users to set /rendering/triangle-directional-lights=false which
falls back to the non-directional implementation of a point.
