* @short_description: Base Class for overlays in a #GESTimelineLayer
*
* Overlays are objects which modify the underlying layer(s).
*
* Examples of overlays include text, image watermarks, or audio dubbing.
*
* Transitions, which change from one source to another over time, are
* not considered overlays.
