compositor: Accumulate damage per plane
When we analyze and accumulate damage prior to repainting, we need to accumulate damage per plane, so that whatever damage a surface contributes is accumulated in the plane that it's assigned to. Before, we would always accumulate damge in the primary plane, which caused repaints in the primary plane whenever a surface in a sprite or framebuffer was damaged. Eliminating this repaint is a big win for cases where we pageflip to a client surface or use a sprite overlay. This also prepares for fixing the missing cursor updates, since we now track damage to the cursor surface in a dedicated sprite plane.
