These calls no longer go through the CompositePicture() hook, so damage was no longer generated for them. This patch simply damages the entire destination clip region. It would be possible to generate tighter damage for certain operators such as Over and Add, where blank source pixels have no effect on the destination, but given that virtually all trapezoid rendering takes place on pixmaps, it's unlikely that anybody would actually benefit from this optimization, and the miTrapezoidBounds function did sometimes show up on profiles, probably because it does several divisions per trapezoid. V2: Call DamageRegionProcessPending() - pointed out by Michel Dänzer. V3: Call DamageRegionProcessPending() *after* rendering - pointed out by Maarten Maathuis Reviewed-by: Michel Dänzer <daenzer@vmware.com> Signed-off-by: Søren Sandmann <ssp@redhat.com>
