Rather than trying to fix up our own heuristics using a `GtkMenuPositionFunc`, use whatever GTK provides to position given a specific rectangle, which also has the benefit of nicely integrating with GDK backends such as Wayland. Another advantage is that we can use GdkGravity to center the popup. Since GTK 3, GtkWidget also gained a "popup-menu" signal, which we can/should use instead of rolling our own context signals.
