Summary: Missing from our surface handling was the damage_buffer call introduced in version 4 of the wl_compositor interface. Its only difference to a normal damage call is that the damaged region is supposed to be defined by the client in buffer coordinates instead of surface coordinates. This damage must be tracked separately in KWayland and on commit with the buffer transformation united with the normal damage. Test Plan: Autotest updated.
