SUMMARY
=======

The Mfccdc sample demonstrates how to set the Mapmode, Viewport, and Window
parameters, and draws a rectangle based on given logical coordinates; then, the
sample calculates the resulting device units.

The sample shows how to use the following functions:

   SetMapMode()
   SetWindowExt()
   SetViewportExt()
   SetWindowOrg()
   SetViewportOrg()
   LPtoDP()
   NormalizeRect()
