Allow Qt graphics callbacks to work again (bug #56857)
* Object.h, Object.cc (Object::do_connections): New virtual method. Do
connections that were previously done in qt_graphics_toolkit::create_object
* qt_graphics_toolkit.cc (qt_graphics_toolkit::create_object): Let
Object::do_connections do the signal/slot connections.
* Figure.h, Figure.cc (Figure::do_connection): Overload Object::do_connections
to also make connections on peer Canvas object.
* Panel.h, Panel.cc (Panel::do_connection): Overload Object::do_connections
to also make connections on peer Canvas object.
