-/**
- * gtk_container_propagate_draw:
- * @container: a #GtkContainer
- * @child: a child of @container
- * @cr: Cairo context as passed to the container. If you want to use @cr
- *   in container’s draw function, consider using cairo_save() and
- *   cairo_restore() before calling this function.
- *
- * When a container receives a call to the draw function, it must send
- * synthetic #GtkWidget::draw calls to all children that don’t have their
- * own #GdkWindows. This function provides a convenient way of doing this.
- * A container, when it receives a call to its #GtkWidget::draw function,
- * calls gtk_container_propagate_draw() once for each child, passing in
- * the @cr the container received.
- *
- * gtk_container_propagate_draw() takes care of translating the origin of @cr,
- * and deciding whether the draw needs to be sent to the child. It is a
- * convenient and optimized way of getting the same effect as calling
- * gtk_widget_draw() on the child directly.
- *
- * In most cases, a container can simply either inherit the
- * #GtkWidget::draw implementation from #GtkContainer, or do some drawing
- * and then chain to the ::draw implementation from #GtkContainer.
