Scenegraph is inherently tight to QtQuick, but it is not your only
option for hardware acceleration inside Qt. E'en in ye goode olde days
I believed there was hardware acceleration somewhere in the pipeline,
for example http://doc.qt.digia.com/qq/qq26-openglcanvas.html . If we
wanted more hardware acceleration of widgets, as I don't know how good
QGLWidget was, I'm pretty sure it would still be extending the "good
old rendering engine" and not switching to Scenegraph. Remember the
tale of the square peg and the round hole.
