compositor: use bounding box for damage regions

Browse Source 
Change weston_surface_damage*() functions to use the full surface
bounding box or call surface_compute_bbox() to find the bounding box for
an arbitrary rectangle.

This should fix all rendering artifacts for non-opaque (i.e. ARGB)
transformed surfaces.
