This allows applying SVG <mask>s to elements. It is only implemented for the simplest (and default) case: - mask-type = luminance - maskContentUnits = maskContentUnits - maskUnits = objectBoundingBox - Default masking area It should be possible to extend to cover more cases. Though the layout for maskContentUnits = objectBoundingBox will be tricky to figure out.
