Returns the character offset for the specified point.
For a typical character, the trailing argument will be filled in to
indicate whether the point is closer to the leading edge (0) or
the trailing edge (1). When the point is over a cluster composed
of multiple characters, the trailing argument will be filled with the
position of the character in the cluster that is closest to
the point.

@param trailing the trailing buffer
@return the character offset
@exception IllegalArgumentException <ul>
<li>ERROR_INVALID_ARGUMENT - if the trailing length is less than <code>1</code></li>
