 * GESEditMode:
 * @GES_EDIT_MODE_NORMAL: The element is edited the normal way (default).

 *  the element by MOVING its toplevel. When acting on the start of the
 *  element (#GES_EDGE_START), this will only MOVE the element, but not
 *  its toplevel parent. This can allow you to move a #GESClip or
 *  #GESGroup to a new start time or layer within its container group,
 *  without effecting other members of the group. When acting on the end
 *  of the element (#GES_EDGE_END), this will END-TRIM the element,
 *  leaving its toplevel unchanged.
 * @GES_EDIT_MODE_RIPPLE: The element is edited in ripple mode: moving
 *  itself as well as later elements, keeping their relative times. This
 *  edits the element the same as #GES_EDIT_MODE_NORMAL. In addition, if
 *  acting on the element as a whole, or the start of the element, any
 *  toplevel element in the same timeline (including different layers)
 *  whose start time is later than the *current* start time of the MOVED
 *  element will also be MOVED by the same shift as the edited element.
 *  If acting on the end of the element, any toplevel element whose start
 *  time is later than the *current* end time of the edited element will
 *  also be MOVED by the same shift as the change in the end of the
 *  edited element. These additional elements will also be shifted by
 *  the same shift in layers as the edited element.
 * @GES_EDIT_MODE_ROLL: The element is edited in roll mode: swapping its
 *  content for its neighbour's, or vis versa, in the timeline output.
 *  This edits the element the same as #GES_EDIT_MODE_TRIM. In addition,
 *  any neighbours are also TRIMMED at their opposite edge to the same
 *  timeline position. When acting on the start of the element, a
 *  neighbour is any earlier element in the timeline whose end time
 *  matches the *current* start time of the edited element. When acting on
 *  the end of the element, a neighbour is any later element in the
 *  timeline whose start time matches the *current* start time of the
 *  edited element. In addition, a neighbour have a #GESSource at its
 *  end/start edge that shares a track with a #GESSource at the start/end
 *  edge of the edited element. Basically, a neighbour is an element that
 *  can be extended, or cut, to have its content replace, or be replaced
 *  by, the content of the edited element. Acting on the element as a
 *  whole (#GES_EDGE_NONE) is not defined. The element can not shift
 *  layers under this mode.
 * @GES_EDIT_MODE_TRIM: The element is edited in trim mode. When acting
 *  on the start of the element, this will START-TRIM it. When acting on
 *  the end of the element, this will END-TRIM it. Acting on the element
 *  as a whole (#GES_EDGE_NONE) is not defined.
 * @GES_EDIT_MODE_SLIDE: The element is edited in slide mode (not yet
 *  implemented): moving the element replacing or consuming content on
 *  each end. When acting on the element as a whole, this will MOVE the
 *  element, and TRIM any neighbours on either side. A neighbour is
 *  defined in the same way as in #GES_EDIT_MODE_ROLL, but they may be on
 *  either side of the edited elements. Elements at the end with be
 *  START-TRIMMED to the new end position of the edited element. Elements
 *  at the start will be END-TRIMMED to the new start position of the
 *  edited element. Acting on the start or end of the element
 *  (#GES_EDGE_START and #GES_EDGE_END) is not defined. The element can
 *  not shift layers under this mode.
 *
 * When a single timeline element is edited within its timeline at some
 * position, using ges_timeline_element_edit(), depending on the edit
 * mode, its #GESTimelineElement:start, #GESTimelineElement:duration or
 * #GESTimelineElement:in-point will be adjusted accordingly. In addition,
 * any clips may change #GESClip:layer.
 *
 * Each edit can be broken down into a combination of three basic edits:
 *
 * + MOVE: This moves the start of the element to the edit position.
 * + START-TRIM: This cuts or grows the start of the element, whilst
 *   maintaining the time at which its internal content appears in the
 *   timeline data output. If the element is made shorter, the data that
 *   appeared at the edit position will still appear in the timeline at
 *   the same time. If the element is made longer, the data that appeared
 *   at the previous start of the element will still appear in the
 *   timeline at the same time.
 * + END-TRIM: Similar to START-TRIM, but the end of the element is cut or
 *   grown.
 *
 * In particular, when editing a #GESClip:
 *
 * + MOVE: This will set the #GESTimelineElement:start of the clip to the
 *   edit position.
 * + START-TRIM: This will set the #GESTimelineElement:start of the clip
 *   to the edit position. To keep the end time the same, the
 *   #GESTimelineElement:duration of the clip will be adjusted in the
 *   opposite direction. In addition, the #GESTimelineElement:in-point of
 *   the clip will be shifted such that the content that appeared at the
 *   new or previous start time, whichever is latest, still appears at the
 *   same timeline time. For example, if a frame appeared at the start of
 *   the clip, and the start of the clip is reduced, the in-point of the
 *   clip will also reduce such that the frame will appear later within
 *   the clip, but at the same timeline position.
 * + END-TRIM: This will set the #GESTimelineElement:duration of the clip
 *   such that its end time will match the edit position.
 *
 * When editing a #GESGroup:
 *
 * + MOVE: This will set the #GESGroup:start of the clip to the edit
 *   position by shifting all of its children by the same amount. So each
 *   child will maintain their relative positions.
 * + START-TRIM: If the group is made shorter, this will START-TRIM any
 *   clips under the group that start after the edit position to the same
 *   edit position. If the group is made longer, this will START-TRIM any
 *   clip under the group whose start matches the start of the group to
 *   the same edit position.
 * + END-TRIM: If the group is made shorter, this will END-TRIM any clips
 *   under the group that end after the edit position to the same edit
 *   position. If the group is made longer, this will END-TRIM any clip
 *   under the group whose end matches the end of the group to the same
 *   edit position.
 *
 * When editing a #GESTrackElement, if it has a #GESClip parent, this
 * will be edited instead. Otherwise it is edited in the same way as a
 * #GESClip.
 *
 * The layer priority of a #GESGroup is the lowest layer priority of any
 * #GESClip underneath it. When a group is edited to a new layer
 * priority, it will shift all clips underneath it by the same amount,
 * such that their relative layers stay the same.
 *
 * If the #GESTimeline has a #GESTimeline:snapping-distance, then snapping
 * may occur for some of the edges of the **main** edited element:
 *
 * + MOVE: The start or end edge of *any* #GESSource under the element may
 *   be snapped.
 * + START-TRIM: The start edge of a #GESSource whose start edge touches
 *   the start edge of the element may snap.
 * + END-TRIM: The end edge of a #GESSource whose end edge touches the end
 *   edge of the element may snap.
 *
 * These edges may snap with either the start or end edge of *any* other
 * #GESSource in the timeline that is not also being moved by the element,
 * including those in different layers, if they are within the
 * #GESTimeline:snapping-distance. During an edit, only up to one snap can
 * occur. This will shift the edit position such that the snapped edges
 * will touch once the edit has completed.
 *
 * Note that snapping can cause an edit to fail where it would have
 * otherwise succeeded because it may push the edit position such that the
 * edit would result in an unsupported timeline configuration. Similarly,
 * snapping can cause an edit to succeed where it would have otherwise
 * failed.
 *
 * For example, in #GES_EDIT_MODE_RIPPLE acting on #GES_EDGE_NONE, the
 * main element is the MOVED toplevel of the edited element. Any source
 * under the main MOVED toplevel may have its start or end edge snapped.
 * Note, these sources cannot snap with each other. The edit may also
 * push other elements, but any sources under these elements cannot snap,
 * nor can they be snapped with. If a snap does occur, the MOVE of the
 * toplevel *and* all other elements pushed by the ripple will be shifted
 * by the same amount such that the snapped edges will touch.
 *
 * You can also find more explanation about the behaviour of those modes at:
 * [trim, ripple and roll](http://pitivi.org/manual/trimming.html)
 * and [clip management](http://pitivi.org/manual/usingclips.html).
