You have access to the scene graph already:

http://doc-snapshot.qt-project.org/5.0/qquickitem.html#updatePaintNode
http://doc-snapshot.qt-project.org/5.0/qsgnode.html
http://doc-snapshot.qt-project.org/5.0/qsggeometry.html
http://doc-snapshot.qt-project.org/5.0/qsgsimplematerialshader.html
http://doc-snapshot.qt-project.org/5.0/qsgmaterial.html

It is a low-level API (and rightly so), but it is there and very much usable.

Things on my mind that we could add in the future:
 - glyph nodes, to support text directly from C++
 - public API for the renderer, so rendering sub graphs in user API is possible.
But lets get Qt 5.0 out first...
