commit bf83bf00a75343f7d1dcd15dc4eeec1b1a4b9428

    test: Add subsurface-image-repeat
    
    Test handling of source clipping with an image - principally to check
    handling of mime types and zero-copy image snapshotting in the vector
    surfaces and ensure that they work with subsurface patterns as well.
