 * GESEditMode:
 * @GES_EDIT_MODE_NORMAL: The element is edited the normal way (default).
 *  This only moves a single element. If acting on the start edge of the
 *  element, the element's start time is set to the edit position.
 *  If acting on end edge of the element, the element's duration time
 *  is set such that its end time matches the edit position.
 * @GES_EDIT_MODE_RIPPLE: The element is edited in ripple mode. This
 *  shifts the element and all later elements (those with equal or later
 *  start times) in the timeline by the same amount. If acting on the
 *  element as a whole, the element's start time is shifted to the edit
 *  position, and later elements are also shifted by the same amount. If
 *  acting on the end edge of the element, the element's **duration time**
 *  is shifted so that the element's end time matches the edit position,
 *  and later elements have their **start time** shifted by the same
 *  amount.
 * @GES_EDIT_MODE_ROLL: The element is edited in roll mode. This trims
 *  the edge of an element and neighbouring edges (opposite edges of other
 *  elements in the timeline with the same corresponding time value), such
 *  that the edges remain in contact. If acting on the start edge of the
 *  element, the start edge is trimmed to the edit position (see
 *  #GES_EDIT_MODE_TRIM), and any other elements in the timeline whose end
 *  time matches the edited element's start time (evaluated before the
 *  edit) will have their **end** edge trimmed to the same edit position.
 *  Similarly, if acting on the end edge of the element, the end edge is
 *  trimmed to the edit position, and any other elements in the timeline
 *  whose start time matches the edited element's end time will have
 *  their start edge trimmed to the same edit position.
 * @GES_EDIT_MODE_TRIM: The element is edited in trim mode. This shifts
 *  the edge of a single element while maintaining the timing of
 *  its internal content in the timeline, so the samples/frames/etc of a
 *  source would still appear at the same timeline time when it is played.
 *  If acting on the start edge of the element, the element's start time
 *  will be shifted to the edit position and the element's in-point time
 *  will be shifted by the same amount. Additionally, the element's
 *  duration time will be shifted the other way such that the element's
 *  end time remains the same. If acting on end edge of the element, the
 *  element's duration time is set such that its end time matches the edit
 *  position.
 * @GES_EDIT_MODE_SLIDE: The element is edited in slide mode (not yet
 *  implemented). This shifts the element and will trim the edges of
 *  neighbouring edges on either side accordingly. If acting on the
 *  element as a whole, the element's start time is shifted to the edit
 *  position. Any other elements in the timeline whose end time matches
 *  the edited element's start time (evaluated before the edit) will have
 *  their end edge trimmed to the same edit position. Additionally, any
 *  other elements in the timeline whose start time matches the edited
 *  element's end time will have their start edge trimmed to match the
 *  edited element's **new** end time.
 *
 * When a single timeline element is edited within its timeline, 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,
 * other elements in the timeline may also have their properties adjusted.
 *
 * In fact, the edit is actually performed on the toplevel of the edited
 * element (usually a #GESClip), which is responsible for moving its
 * children along with it. For simplicity, in the descriptions we will
 * use "element" to exclusively refer to toplevel elements.
 *
 * In the edit mode descriptions, the "start edge", "end edge" and the
 * "element as a whole" correspond to using #GES_EDGE_START, #GES_EDGE_END
 * and #GES_EDGE_NONE as part of the edit, respectively. The "start time",
 * "duration time" and "in-point time" correspond to the
 * #GESTimelineElement:start, #GESTimelineElement:duration and
 * #GESTimelineElement:in-point properties, respectively. Moreover, the
 * "end time" refers to the final time of the element:
 * #GESTimelineElement:start + #GESTimelineElement:duration. Finally,
 * the "edit position" is the timeline time used as part of the edit.
 *
 * 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).
