The classic OSMesa renders directly into user memory using src/mesa/swrast, while gallium OSMesa renders using softpipe or llvmpipe and copies out at glFlush() time. This would make gallium look like a worse choice for OSMesa, except that swrast is: 1) Painfully slow to render compared to llvmpipe 2) Incorrect at derivatives 3) Limited to GL 2.1 instead of GL 4.6 In my survey of OSMesa users, debian was the remaining holdout with classic OSMesa in use on hurd and some rare non-LLVM-supported architectures (sh4, alpha, etc.). As of today, they've switched to softpipe-based gallium OSMesa for them. To prevent people from running the wrong OSMesa (to the extent that running OSMesa can ever be the right thing), delete the classic version.
