------- Additional Comments from Zoltan Herczeg <zherczeg at webkit.org>
Ok, now the patch working nicely now. Many web pages can be rendered now, and
Qt doing antialias on QImages, so the pages are nice. There are still missing
GraphicsContext features though, I will finish them soon.

Unfortunately the RenderThemeQt puts QPixmaps to the QPicture, and it cannot be
replayed on the thread. Do you have any idea to avoid these QPixmaps?

We can also experiment with differnt setups, like put the WebKit into a thread,
and do all drawings in the gui thread, or something different. Anyway, is it
really imposible to use QPixmaps in a thread? Is there a workaround for them?
Creating multiple QApplication-s or something?
