    saa, vmwgfx: Fix saa_copy_composite
    
    The traditional accelerated copy methods aren't format aware.
    Make saa copy format aware,and pass formats on to the driver copy function
    if available. If the driver can't handle format conversions it needs to
    return FALSE.
    
    This fixes format confusion in the copy composite fastpath.

    saa: Always read back hw contents on poly_fill_rect
    
    The damage region may be much larger than the actual area
    filled, so make sure we read back any hw contents in the damage region
    since we use it to mark sw dirty.
    Revisit this in the future since it may increase readbacks in an
    undesired way. There are workarounds.

    saa: Only try to accelerate pixmaps that are driver pixmaps
    
    Trying to accelerate scratch pixmaps doesn't work currently,
    and I'm not sure it's a big benefit either.
    
    This is in line with what EXA does.
