compare-render: Create rotated reference without gdk-pixbuf

Browse Source 
We use the renderer to create the reference for the rotate test by
applying the same rotate transform to the reference image instead of the
tested node.

This is somewhat suboptimal because they run very similar codepaths, but
this method works with high bit depth content and different colorstates

This concludes the port away from gdk-pixbuf and means that all rendered
content and reference images can now use high bit depth and colorstates.
