Perspective transforms need special handling in OpenVG. However, that
was only done for rounded rectangles. Enable it for zero-radius
rectangles too.

The current approach to rendering paths (used by Rectangles and Glyph
nodes) does not support rendering with non-affine transformations. That
is because OpenVG does not support passing a non-affine transformation
matrix when rendering paths. So instead when using a non-affine
transform we will fallback to rendering to an offscreen VGImage, then
rendering that as an image which can have a perspective transform.

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.
