generated somewhat, with all TEX instructions now emitted at the head
of the program.

Try not to use the same temp reg as a TXP destination more than once,

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.
