Add a facility to route all rasterization through a fragment program
which is automatically generated to match the current texture environment state. Introduces a new value ctx->FragmentProgram._Active which is true when either _Enabled is true or there is such a fragment program ready to run. To test out on a driver running the software rasterizer, set MESA_TEX_PROG=t in the environment. It goes without saying that performance is lower for the software rasterizer in this mode.
