This feature is finally reimplemented correctly. Everyone please test heavily. I want to hear about any workflow or usability issues from all kinds of users.
* The position of the center (axis) of rotation and skewing used by Selector is now remembered for all objects and is restored when you select those objects again (even after save and reload). When you move or scale an object, its rotation center is moved or scaled too, so its position relative to the object always remains the same.
* Shift+click on the rotation center resets it back to the center of the object's box.
* Consequently, dragging the transformation center is now an undoable action; you can press Ctrl+Z to undo the drag.
Todo:
- make use of this in keyboard transforms and Transform dialog;
- make it work smartly for groups: if a group has center not set, return the center of the first object inside group with the center set
