/**
* ges_simple_timeline_layer_add_object:
* @layer: a #GESSimpleTimelineLayer
* @object: the #GESTimelineObject to add
* @position: the position at which to add the object
*
* Adds the object at the given position in the layer. The position is where
* the object will be inserted. To put the object before all objects, use
* position 0. To put after all objects, use position -1.
*
* When adding transitions, it is important that the adjacent objects
* (objects at position, and position + 1) be (1) A derivative of
* GESTimelineSource or other non-transition, and (2) have a duration at least
* as long as the duration of the transition.
*
* The layer will steal a reference to the provided object.
*
* Returns: TRUE if the object was successfuly added, else FALSE.
