    uxa: Fix compatible_formats() for OVER
    
    In separating the boolean logic out into a separate function, dc6522dd,
    I reversed the sense of one particular test:
    
      src->format == dst->format
    
    The OVER optimisation is only valid if the src and dst formats match,
    but not always.
