Quick: Do not calculate the difference in a geometryChange
This difference is only used by the ListView, so calculating it and
storing it (on the stack) introduces a penalty for all items. As the new
geometry is already applied, the old geometry is passed along. This has
the added advantage that the ListView does not have to re-calculate that
either. This fixes a performance regression.
