    sna: Fix the depth/format on the temporary shadow Pictures

    When scaling the output, we re-render onto the scanout using a call to
    Composite, for which we create temporary Pictures. In most cases, the
    mismatching depth/format goes unnoticed, but along one particular
    fallback path, we use those to create a new Picture but the mismatching
    format results in a segfault.

    sna: Handle bad picture format/depth mismatches

    Scaling the output feed in an invalid picture->format/depth combination
    which causes the fallback downsampling function to explode. Whilst this
    is a bug in the higher layer, we can handle the error anyway.
