Queue rect updates for each frame (and.. maybe? do rects in parallel)

Browse Source 
both superqemu and vncvm have supported this but I never did it for some reason. its noticably faster than before. testing seems to imply that its actually slightly faster without the batcher enabled (maybe because it's actually able to split the work now if I had to guess)
