* app/composite/: Regenerated installers and testers. * app/composite/make-install.py: increased tests of pixels to 1024*1024+1 * app/composite/gimp-composite-mmx.c (gimp_composite_overlay_rgba8_rgba8_rgba_mmx): Backed out of the current build. Although the unit tests all pass, the emperical evidence is that something is wrong with it.
