QSvgRenderer does not handle transform="rotate(...)" x and y properly.

I have a simple application that renders an SVG into a PNG. I found that when I added rotated texts they would not be shown. Deeper digging took me to find out that in transform="rotate(angle, x, y)" the center is not handled properly by Qt. I attach an example SVG that looks the same on webkit, inkscape, rsvg-convert converts well but Qt doesn't.
