 * @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.
