Zoom Sample
C# Implementation details
All implementation is contained in the main form class named ZoomForm.
OnZoom() handler converts screen coordinates of the zoom center to
global 3D coordinates using IView_DG.ScreenTo3DEx.
The point has to be converted to local to the Eye frame to use the
ILook.ZoomEx
method. This is accomplished via IFrameEx.ToLocal.for
the IFrame of the Eye Frame.
