* Helper function to choose and instantiate one of the software rasterizers:
21
* cell, llvmpipe, softpipe.
23
* This function could be shared, but currently causes headaches for
24
* the build systems, particularly scons if we try. Long term, want
25
* to avoid having global #defines for things like GALLIUM_LLVMPIPE,
26
* GALLIUM_CELL, etc. Scons already eliminates those #defines, so
27
* things that are painful for it now are likely to be painful for
28
* other build systems in the future.
