A list is fine too and I think it actually is even better.  We can use 
also this for sdl/vnc rendering then.  Right now qxl-render.c calls 
update_area(), then waits for the results (including the dirty rects). 
We can just call update_area_async instead and receive the updates 
rectangles via surface_updated callback.  That way we can also simplify 
update_area_async, no need to pass around the rectangles list.

cheers,
   Gerd
