Add (back) properties to QGraphicsItem to change the transformations component

This reapply commit 8ad5020940f10d4ecc5c5e8b3b9656531cb84ef3 and its
dependent change that has been reverted while rebasing the
recursivepaint branch.

With the new properties it is possible to easily animate transformations
