Assets to duplicate the problem

If the repeat mode is 'no-repeat' for SVG content brought in as a mask, then the unpainted background of the SVG artwork is treated as opaque white.

If the repeat mode is 'repeat' for SVG content brought in as a mask, then the unpainted background of the SVG artwork is treated as transparent.

This is inconsistent and problematic. The background should always be treated as transparent. Not doing so forces the creation of masks that are as bigger in order to be able to use 'repeat' but this will likely require larger framebuffers and longer execution time.

This may be related to bug 48471.
