change of behavior of rotate-tabular and rotate-cell toolbar buttons such that they toggle the rotation. Therefore a toggle feature is added to the tabular features. Moreover after the patch the state of the set-rotate-cell and toggle-rotate-cell buttons is on only if all selected cells in the table are rotated. If not all selected cells are rotated then the toggle button rotates all selected cells.
The toggle-icons are copied from the set-icons.
