Log Message:
-----------
backend_gtk: don't use idle events for draw_rubberband.
Use of idle events for draw_rubberband was a peculiarity of backend_gtk.
When using zoom-to-rect, it often caused a rubberband draw event
to occur after the canvas redraw at the end of the zoom, leaving
the canvas showing the state before the zoom action instead of
showing the result of the action.
