It definitely says it's supposed to, but that doesn't seem to be true. I traced
the advance function through and it doesn't ever update the actual scene graph.
It finally eventually reaches AnimatorController, which at the lowest level
just calls commit on a job, which in its base class is completely empty, and
doesn't do much in the one derived class:

> if (!wasChanged || !node)

> m.translate(dx, dy);
> m.translate(ox, oy);
> m.scale(scale);
> m.rotate(rotation, 0, 0, 1);
> m.translate(-ox, -oy);
> node->setMatrix(m);
>
> wasChanged = false;
> }
>
> void QQuickTransformAnimatorJob::commit()
> {
> if (m_helper)
> m_helper->commit();

Then it calls update() to refresh the window. That's it. From the name, advance
is clearly supposed to actually advance something, but it doesn't. So this is
definitely a Qt bug.
