I profiled the entire set of libraries and one thing sticks out greatly:
Each sample counts as 0.01 seconds.
% self self total
time seconds calls ms/call ms/call name
90.93 174.85 6092 28.70 28.70 pixman_fill_rect_32bbp
1.15 2.21 141053 0.02 0.06 IcRasterizeTrapezoid
0.77 1.49 1963553 0.00 0.00 IcBuildCompositeOperand
At least in my test here, pixman_fill_rect_32bbp is by far the biggest
user of time.
Are there possibly some super-fast routines that would work here?
Filling a rectangle is so common that I would think there are a ton of
options here. Possibly using hardware acceleration since just about
every computer has some sort of blitter available.
