Hazen, wouldn't it be fairly straightforward to infer from the good svgcairo results what to do for the other cairo file devices to get proper transparent backgrounds for those devices? My feeling is it would be easier to deal with the cairo file devices first since their code is similar to the svgcairo case and much simpler than in the xcairo case. Similarly, I think that whoever tackles the qt case should attempt to expand the good svgqt transparent background results to the other qt devices before finally attempting to deal with the complicated qtwidget case.
