A few years ago Phil Blundell made patch to speed up pixel operations (scale, blend,
rotate, etc) a lot for systems without a floatingpoint unit. Years of gtk+ developer
desinterest have let the patch bitrot a fair deal.
In order to get the ball rolling again I updated the autotools bits in the patch and
adjusted the indices so it applies to the .c files as well. What's left is updating the
functions and their arguments to catch up with several years worth of development.
This patch would speed up the GUI on openmoko based systems a lot, since it's using quite
a lot if pixmaps.
I've heard that the openmoko team also tried sapwood, but couldn't get it to work properly
because it's a) entirely undocumented and b) only supports 1 bit alpha
Any heroes that want to give a shot at updating the pixops patch?
