Sets the property of a child of the element.
property_name can either be in the format "prop-name" or "TypeName:GESTimelineElement:prop-name", where
"prop-name" is the name of the property to set (as used in @set), and
"TypeName" is the type name of the child (as returned by G_OBJECT_TYPE_NAME). The latter format is useful when two children
of different types share the same property name.
The first child found with the given "prop-name" property that was registered with
add_child_property (and of the type "TypeName", if it was given)
will have the corresponding property set to value. Other children that may have also matched the property name (and type name
) are left unchanged!
