Remarks

HitTest returns a boolean value indicating whether or not the current element is intersected by the specified coordinate pair and tolerance distance.  For instance, if we have a line element selected, the HitTest is determining whether that line element is within the specified tolerance from the given X and Y.  A value of TRUE is returned if the element is within the tolerance, while FALSE is returned if it is not.

The X,Y, and tolerance values should be specified in map units.
