* 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.

and call figure's appropriate callback.
* Canvas.h (Canvas::updateCurrentPoint): New method.
* Canvas.cc (Canvas::updateCurrentPoint): Likewise. Update figure and
child axes currentpoint property.
