swrast: Use fixed-function processing instead _TexEnvProgram for DrawPixels
This is a hack to work around drivers such as i965 that:
- Set _MaintainTexEnvProgram to generate GLSL IR for
fixed-function fragment processing.
- Don't call _mesa_ir_link_shader to generate Mesa IR from the
GLSL IR.
- May use swrast to handle glDrawPixels.
Since _mesa_ir_link_shader is never called, there is no Mesa IR to
execute. Instead do regular fixed-function processing.
Even on platforms that don't need this, the software fixed-function
code is much faster than the software shader code.
NOTE: This is a candidate for the 8.0 branch.
