* Obtains the motion history for a pointer device; given a starting and
* ending timestamp, return all events in the motion history for
* the device in the given range of time. Some windowing systems
* do not support motion history, in which case, %FALSE will
* be returned. (This is not distinguishable from the case where
* motion history is supported and no events were found.)
*
* Note that there is also gdk_surface_set_event_compression() to get
* more motion events delivered directly, independent of the windowing
* system.
*
* Returns: %TRUE if the windowing system supports motion history and
* at least one event was found.
