Sets a dialog modal or non-modal. Modal dialogs prevent interaction
with other windows in the same application. To keep modal dialogs
on top of main application windows, use
gtk_native_dialog_set_transient_for() to make the dialog transient for the
parent; most [window managers][gtk-X11-arch]
will then disallow lowering the dialog below the parent.
