+	Set the window title for labwc to use when nested in a compositor.
+	<fmtstr> is a format string to be used as the window title, replacing
+	`%o` with the name of the output region. This is useful when simulating
+	multiple screens, such as with running labwc with the enviornment
+	variable `WLR_WL_OUTPUTS=2`. In this case, `%o` will be unique per
