[OpenVG] Implement more graphics primitives
Created attachment 47726 [details]
This patch should be pretty straightforward, and does exactly what the title says.
I'm also cleaning up some unnecessary indirections in GraphicsContextOpenVG's rectangle wrapper code, which don't make a lot of sense since (after the last patch has been changed from its original version) m_data is now the painter itself, instead of a wrapper class that holds the painter.
Please review, thanks!
