libcm/app/cmTimeLine.c
kevin caffeb4b0a cmTimeLine.c : _cmTimeLineObjAtTime() changed such that when an object contains 
the search point that the returned object also contains the search point.
The returned object will be the one containing the search point whose begin or
end point is closest to the search point.
