  This class realizes resizing of selected items on behalf of its parent mode.
  The user presses the mousebutton at one of the framehandles, drags it to the end point
  and releases the mousebutton. The item or group selection is resized to the new dimensions.
  During the move the selected items are highlighted.

                Prepares the gesture for resizing the selection

          This method only sets the m_handle field.
          If the correct value is set by prepare() (default = SOUTHEAST),
          it's not necessary to call this method.
