Related to the recent discussion on some problems of Qt SVG renderer when drawing the Oxygen icons, I decided to sit down and wrote an example of yet-another SVG renderer by using QtWebKit (available since Qt 4.4.0). Check out the code if you're interested, it is part of the Graphics Dojo examples.
The major difference between this WebKit-based tool compared to QSvgRenderer is that it should handle SVG features which are supported by WebKit. Note that QtSvg limits itself only to SVG Tiny 1.2 without DOM API and scripting (due to various reasons). On the other hand, SVG support in WebKit will be improved over the time. Yes, fancy stuff like filter effects are not fully implemented yet (at least, in QtWebKit), but we are working towards that.
