Finds the TrackElement-s controlled by the clip that match the given criteria.
If track is given as null and track_type is given as
UNKNOWN, then the search will match all elements in any track, including those
with no track, and of any track_type. Otherwise, if track is
not null, but track_type is UNKNOWN
, then only the track elements in track are searched for. Otherwise, if track_type is not
UNKNOWN, but track is null, then
only the track elements whose track_type matches track_type
are searched for. Otherwise, when both are given, the track elements that match **either** criteria are searched for. Therefore, if you
wish to only find elements in a specific track, you should give the track as track, but you should not give the track's
track_type as track_type because this would also select elements
from other tracks of the same type.
You may also give type to _further_ restrict the search to track elements of the given type.
