windowbuttonmotionfcn callback is defined.
(Figure::update): Enable mouse tracking on canvas and all child widgets
when windowbuttonmotionfcn is defined.
* Panel.cc (Panel::Panel): Propagate mouse tracking to child widgets
during initialization.
* Container.h (Container::childEvent): New method.
* Container.cc (Container::childEvent): Likewise. Propagate mouse
tracking status to child widgets.
* BaseControl.cc (BaseControl::eventFilter): Handle mouse move events
and call figure's appropriate callback.
* Canvas.h (Canvas::updateCurrentPoint): New method.
* Canvas.cc (Canvas::updateCurrentPoint): Likewise. Update figure and
child axes currentpoint property.
(Canvas::canvasMouseMoveEvent): Update currentpoint properties and call
windowbuttonmotionfcn callback.
(Canvas::canvasMousePressEvent): Call updateCurrentPoint.
