    Need to byte-order swap the alpha mask as well in this case.

    ximagesink: add support for 32-bit RGB with alpha mask

    When X screen return a depth = 32 with bpp = 32, the alpha mask
    must be correctly set to have a known GStreamer video format.
    X visual structure doesn't provide the alpha mask information,
    but we can find it from the others masks.
