/**
 * GtkGrid is a container which arranges its child widgets in
 * rows and columns. It is a very similar to #GtkTable and #GtkBox,
 * but it consistently uses #GtkWidget’s #GtkWidget:margin and #GtkWidget:expand
 * properties instead of custom child properties, and it fully supports
 * [height-for-width geometry management][geometry-management].
 * 
 * Children are added using gtk_grid_attach(). They can span multiple
 * rows or columns. It is also possible to add a child next to an
 * existing child, using gtk_grid_attach_next_to(). The behaviour of
 * GtkGrid when several children occupy the same grid cell is undefined.
 * 
 * GtkGrid can be used like a #GtkBox by just using gtk_container_add(),
 * which will place children next to each other in the direction determined
 * by the #GtkOrientable:orientation property.
 * 
 * # CSS nodes
 * 
 * GtkGrid uses a single CSS node with name grid.
