improve mouse zooming for Qt plotting (bug #44302)
* Figure.h (enum MouseMode): Split ZoomMode into ZoomInMode and
ZoomOutMode. Change all uses.
* Canvas.cc (Canvas::canvasMouseReleaseEvent,
Canvas::canvasWheelEvent): Make meaning of zoom factor consistent with
zoom function. Make direction of wheel event consistent with other
programs.
* __init_fltk__.cc (plot_window::handle): Make meaning of zoom factor
consistent with zoom function.
* MouseModeActionGroup.cc (MouseModeActionGroup::MouseModeActionGroup):
Provide buttons for zooming in and out.
* graphics.cc (figure::properties::set_toolkit): Handle zoom direction.
(do_zoom): Make factor > 1 zoom in.
