    About the timing of gfx operations:

    The 34010 manual lists a fairly intricate and accurate way of
    computing cycle timings for graphics ops. However, there are
    enough typos and misleading statements to make the reliability
    of the timing info questionable.

    So, to address this, here is a simplified approximate version
    of the timing.

        timing = setup + (srcwords * 2 + dstwords * gfxop) * rows

    Each read access takes 2 cycles. Each gfx operation has
    its own timing as specified in the 34010 manual. So, it's 2
    cycles per read plus gfxop cycles per operation. Pretty
    simple, no?
