gtkwidget: Avoid doubly coordinate conversion when emulating press

Browse Source 
We are poking again into the event propagation machinery, which
expects events in toplevel coordinates. Since we can't fetch the
original event back at this point, translate the coordinates
back to the toplevel so the emulated press ends up in the right
place.
