/* The contents of a selection are returned in a GtkSelectionData
 * structure. selection/target identify the request.  type specifies
 * the type of the return; if length < 0, and the data should be
 * ignored. This structure has object semantics - no fields should be
 * modified directly, they should not be created directly, and
 * pointers to them should not be stored beyond the duration of a
 * callback. (If the last is changed, we'll need to add reference
 * counting.) The time field gives the timestamp at which the data was
 * sent.
