For now, undo/redo need to be rewritten, so they are disabled.
I also disabled the part handling shape selections.
I have rewritten the part calculating the scale factors/translation vector/rotation angle from the mouse movement.
I added a workaround to transform the selection itself, because i can't manage to move properly a pixelSelection (KisPaintDevice::move deprecated ?).
Got rid of all the artefacts by calculating properly the rectangles of the canvas to be updated.

Next step is to support undo/redo actions, and shape selection transformations again.
Then i can really add new functionalities to the tool.
