* @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.
