API: Export gtk_container_snapshot_child()

It's equivalent to gtk_container_propagate_draw() and then one is
public, too.

/**
* gtk_container_snapshot_child:
* @container: a #GtkContainer
* @child: a child of @container
* @snapshot: $GtkSnapshot as passed to the container. In particular, no
* calls to gtk_snapshot_translate_2d() should have been applied by the
* parent.
*
* When a container receives a call to the snapshot function, it must send
* synthetic #GtkWidget::snapshot calls to all children. This function
* provides a convenient way of doing this. A container, when it receives
* a call to its #GtkWidget::snapshot function, calls
* gtk_container_snapshot_child() once for each child, passing in
* the @snapshot the container received.
*
* gtk_container_snapshot_child() takes care of translating the origin of
* @snapshot, and deciding whether the child needs to be snapshot. It is a
* convenient and optimized way of getting the same effect as calling
* gtk_widget_snapshot() on the child directly.
