Eric, are you sure software render was never implemented?

I am pretty sure that if you bring up EGL GBM platform and you miss a hardware
driver, it will use llvmpipe and it will get stuff on screen (even if it has
synchronization issues). I have had to patch Mutter to explicitly check for
llvmpipe et al. and stop using EGL GBM in that case in favor of another path
that does not suffer from the synchronization issues.

Is there a significant difference between the automatic fallback to llvmpipe
and using LIBGL_ALWAYS_SOFTWARE? Maybe one should use EGL_SOFTWARE=1 or such,
does that still exist?
