Remove existing broken maxX/maxY code for composite (results in infinite

loops, doesn't deal with failure, doesn't present the interface to
    drivers that I expected) and instead replace it with a simple fallback
    to software when coordinate limits could be violated. Act similarly in
    other acceleration cases as well.
The solution I want to see (and intend to do soon) is to (when necessary)
    create temporary pictures/pixmaps pointing towards the real ones' bits,
    with the offsets adjusted, then render from/to those using adjusted
    coordinates.
