There is no "correct" sollution for this. One can provide a common API
for rasterization, but not for all kinds of acceleration. Drivers which
implements such a common API are called mini client drivers (in the SGI
/ MS OpenGL driver kit).

There allready exist a minor API in Mesa for rasterization, which means
a driver can accellerate these.

Better cards need fine-tuned implementations. They are called
Installable client drivers.
