Correct implementation of BView::CopyBits() in ServerWindow, implementation of CopyRegion in DisplayDriverPainter that sorts the rects topologically depending on direction and does the copy in place, obtaining a speedup of about 250%. TODO: extract the sorting algorithm so that it can be reused for the hardware accelerated version later.
