What's a "normal device context"?

The OSMesa driver will use the triangle functions in src/OSmesa/osmesa.c
whenever possible.  Otherwise, the triangle functions in src/triangles.c
will be used.

There are lots of different triangle functions for flat/smooth shading,
RGB/CI mode, textured/untextured, etc.  You may have to modify all of
them if you want your new feature to be pervasive.
