Carlos Garnacho 5aeabdb3d4 gdk/wayland: Perform xdg_activation on gdk_toplevel_set_startup_id 
This call has everything to perform activation as specified by the
xdg_activation protocol, notably a surface to activate as opposed to
gdk_display_notify_startup_complete().

Make activation happen here, so that the surface gets activated when
its gets a startup ID assigned.

* position (100,100). Furthermore, if a positioned is placed in the middle
