Tear down the Design canvas at shutdown

Browse Source 
The Design tab's viewport is the fourth GLCanvas3D on the shared GL context and
the only one the plater does not own, so unbind_canvas_event_handlers() and
reset_canvas_volumes() never reached it — the macOS Command+Q and Debian cases
those calls exist for. Its frame-level handlers become members so they can be
unbound.
