causes corruption in emerald window decoration buttons.

It appears the buttons are completely transparent (show desktop background instead of title bar background).

Using git libdrm and mesa 7.7 (non-git version).

    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.
