* Fix crashes when dragging the bounding box/transform cage of a 0-scale shape.
* Fix crashes when dragging the pivot point of a 0-scale shape
* Fix rotation computation on DAffine2 when scale.x is 0, avoids Nan display
* remove remaining log::info that I introduced in earlier commit
* Fix crash when updating the scale of a transform that was already 0.
* Fix NumberInput behaviour when the requested value changed is does not happen.
* Fix rotation computation when Scale X and Scale Y are both 0. Display 0. This also fixes crashes when modifying the rotation in such case
