Remarks

Update notifies the snapping feedback object that changes in the snap location may have occurred.  The Update method uses the snapResult object that is passed in to display the snapping symbol and snap tip if a snap occurred, and draws them on the hDC passed in.  Calls to Update are usually made in conjunction with calls to IPointSnapper.Snap() inside a tools MouseMove() method.  Even if a null snap result is returned, your code should ensure that Update is called; a null SnapResult passed into the Update method() is fine.
