OpenVG Scenegraph Adaptation
This is an OpenVG backend for the Qt Quick 2 scenegraph.
Should be feature complete now, but there are still some issues that
could be improved in future commits:
If Rectangle nodes are rendered with a non-affine transform, they will
be rendered incorrectly. This is because paths expect affine
transformations.
The Glyph cache is a bit cheeky in that it's caching paths, but doing
so per font size. It shoudln't need to, but right now I've not though
up a good way of getting the transform/scale needed when rendering yet.
