present

Present @toplevel after having processed the GdkToplevelLayout rules.

If the toplevel was previously not showing, it will be showed, otherwise it will change layout according to @layout.

GDK may emit the signal@Gdk.Toplevel::compute-size signal to let the user of this toplevel compute the preferred size of the toplevel surface.

Presenting is asynchronous and the specified layout parameters are not guaranteed to be respected.
