I'm not sure I understand what you are asking for. But I can describe
to you what is happening. When you set the rotation center, none of the
transforms are updated until the mouse moves again. The view's
translation is being stored in the xtrans and ytrans variables. When
the transforms are integrated, the translation is calculated based on
the current rotation center. What behavior are you looking for?
