    gl: Support for non-texture sources and masks
    
    If a GL surface is not a texture and is used as source or mask,
    fall back to using an image surface as an intermediary.
    
    Fixes subsurface-image-repeat, subsurface-modify-child,
    subsurface-modify-parent, subsurface-outside-target, subsurface-pad,
    subsurface-reflect, subsurface-repeat, and subsurface-scale.
