With just a few MULs per pixel, we can detect if a 32x32 blocks starting at that pixel appears in the previous frame. This should basically be as good as any scrolling/copyarea hint we could've gotten from X or a toolkit, and it detects duplicate blocks in may cases where applications don't scroll but just re-render (like resizing). And of course this technique applies to both fullscreen remote display or per-window remote display.
