qt_svg is a trivial app rendering scaling/rotating SVG using Qt's OpenGL code and showing the fps. It's made to follow NVIDIA nvpr_svg code from http://developer.nvidia.com/nv-path-rendering
The repository also has a patch to nvpr_svg which makes it open a new window and use Qt OpenGL instead of the raster engine to render the content.
You can start qt_svg by simply typing
After applying a patch to nvpr_svg you can start it as:
./nvpr_svg -nosync -svg svg/complex/tiger.svg -spin -animate
right click on the window select "Toggle Cairo/Qt software rendering" and click on the newly creted window.
