request_mode	a function to retrieve the `GtkSizeRequestMode` of the widget using the layout; the default request mode is gtk_size_request_constant_size
measure	a function to measure the widget using the layout manager
allocate	a function to allocate the children of the widget using the layout manager

Returns:

the newly created `GtkCustomLayout`
