I just did a little comparison:
| surface time |
surface := AthensCairoSurface extent: 200@200.
surface drawDuring: [ :canvas|
canvas setPaint: Color red.
canvas setShape: (0@0 extent: 100@100).
time := [ 10000 timesRepeat: [ canvas draw ] ] timeToRun.
].
time
0:00:00:00.115
=============
same as above but with:
canvas setPaint: (ThemeIcons current backIcon).
time
0:00:00:00.093
===========
same as above but with:
(canvas setPaint: (ThemeIcons current backIcon)) repeat.
time
0:00:00:00.956
as you can see, even in slowest case, the throughput is:
100*100*10000 = 100'000'000 pixels (texels) per second.
