Make input region double-buffered as specified in the new protocol. While doing it, get rid of the undef region code, and instead use a maximum sized real pixman region. This avoids special-casing regions that might sometimes be undef. As the input region is now usable by default instead of undef, weston_surface_update_transform() does not need to reset the input region anymore. weston_surface_attach() no longer resets the input region on surface size change. Therefore, also weston_seat_update_drag_surface() does not need to reset it. Update toytoolkit to set input region before calling wl_surface_commit() or swapBuffers (which does commit).
