GTK3: dw_menu_popup() on GTK has always ignored the coordinate paramaters and just created the menu where the cursor was. A new API gtk_menu_popup_at_rect() was created to use a rectangle to place the menu, so I had tried to use that... however either it does not work right or I don't understand how to call it. So I have switched to gtk_menu_popup_at_pointer() to stay consistent with the old behavior for now.
