* native_window_set_surface_damage(..., android_native_rect_t* rects, int numRects)
* Set the surface damage (i.e., the region of the surface that has changed
* since the previous frame). The damage set by this call will be reset (to the
* default of full-surface damage) after calling queue, so this must be called
* prior to every frame with damage that does not cover the whole surface if the
* caller desires downstream consumers to use this optimization.
*
* The damage region is specified as an array of rectangles, with the important
* caveat that the origin of the surface is considered to be the bottom-left
* corner, as in OpenGL ES.
*
* If numRects is set to 0, rects may be NULL, and the surface damage will be
* set to the full surface (the same as if this function had not been called for
* this frame).
