Georges Basile Stavracas Neto b63e104561 clutter/paint-nodes: Expose ClutterRootNode
The ClutterRootNode paint node is theoretically the
top-most node of a paint nodes tree, except that we
are not in the point of having full rendering trees
in Clutter (all rendering performed by paint nodes
is still local and immediate).

When controlling the rendering tree, MetaShapedTexture
may need to paint into an offscreen framebuffer under
some circumstations.

Expose ClutterRootNode so that MetaShapedTexture can
use it to render to offscreen framebuffers.
