<pre>commit 5df8ecac5d31467122a9d8bda6241d5957ae6848

compositor: Fix partial repaints
Partial repaints have been broken since the introduction of the atomic
surface updates. The problem was that surface_commit would set the
geometry dirty flag unconditionally, causing transform updates on every
frame which would in turn cause weston_surface_damage_below() to damage
the whole surface area.
This patch changes this so that flag is only set if the pending buffer
has a different size, the location of the surface changed or the opaque
region changed.
Note that changing the opaque region will cause a full repaint of the
affected surface, because of the transform update.
