These two tests currently fail only for the PS backend, but they've done so since before the last major release. The final image result we're getting is definitely wrong in both cases, but we have not yet been able to verify if this is due to bugs in cairo (generating PostScript) or in ghostscript (interpreting and rasterzing the PostScript).
