Gets 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 get (as used in @get), 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 copied into value.
Note that ges_timeline_element_get_child_properties may be more convenient for C programming.
