QGraphicsItem discard updates when it shouldn't.
Once a _q_processDirtyItems call is queued, it means we at least have
one item that is marked as dirty and we must reset it when the
_q_processDirtyItems slot is called. The problem however, was that
we didn't reset the item's dirty state if a full scene update occurred
in between, i.e. item->update(); scene.update();
We don't have to calculate the item's dirty rect if a full scene update
occurs in between, but we still have to reset its state.
Auto-test included.
