[image] Discard redundant clears
On slow machines the call to pixman_fill_sse2() on similar surfaces that
we know are already zeroed takes a significant amount of time [12.77% of
the profile for a firefox trace, cf to just 3% of the profile is spent
inside memset].
Rather than solve why the pixman_fill_sse2() is so slow, simply skip the
redundant clears.
