* @short_description: Base Class for sources of a #GESLayer
*
* #GESSourceClip-s are clips whose core elements are #GESSource-s.
*
* ## Effects
*
* #GESSourceClip-s can also have #GESBaseEffect-s added as non-core
* elements. These effects are applied to the core sources of the clip
* that they share a #GESTrack with. See #GESClip for how to add and move
* these effects from the clip.
