What is the status with OSMesa and llvmpipe?
OSMesa only works with the legacy swrast driver, not llvmpipe. One thing on
my to-do list is to write a gallium state tracker to implement OSMesa for
gallium drivers. But I don't know when I'll get to that.
OSMesa does software offscreen rendering? Why wouldn't developers just
use FBOs these days? Beyond not depending on OSMesa, they'd have
hardware acceleration.
I think it's mostly legacay apps that use OSMesa. But some OSMesa
apps do unusual things like directly touching the color/depth buffer
values to avoid glRead/DrawPixels (see the
OSMesaGetDepth/ColorBuffer() functions).
