commit d6b7f96fde1add92fd11f5a75869ae6fc688bf77

    Fill alpha on xrgb images.

    Do not try to fixup the alpha in the ff/shaders as this has the
    side-effect of overriding the alpha value of the border color, causing
    images to be padded with black rather than transparent. This can
    generate large and obnoxious visual artefacts.

    Fixes:

      Bug 17933 - x8r8g8b8 doesn't sample alpha=0 outside surface bounds
      http://bugs.freedesktop.org/show_bug.cgi?id=17933

    and many related cairo test suite failures.
