  CPoint SetWindowOrg( int x, int y );
  CPoint SetWindowOrg( POINT point );
 
  Parameter   Description
 
  <x>         Specifies the logical x-coordinate of the new origin of the
              window.
 
  <y>         Specifies the logical y-coordinate of the new origin of the
              window.
 
  <point>     Specifies the logical coordinates of the new origin of the
              window. You can pass either a POINT structure or a
              CPoint object for this parameter.
 
  Remarks
 
  Sets the window origin of the specified device context. The window,
  along with the device-context viewport, defines how GDI maps points in
  the logical coordinate system to points in the device coordinate
  system.
 
  The window origin marks the point in the logical coordinate system from
  which GDI maps the viewport origin, a point in the device coordinate
  system specified by the SetWindowOrg function. GDI maps all other points
  by following the same process required to map the window origin to the
  viewport origin. For example, all points in a circle around the point at
  the window origin will be in a circle around the point at the viewport
  origin. Similarly, all points in a line that passes through the window
  origin will be in a line that passes through the viewport origin.
 
  Return Value
 
  The previous origin of the window as a CPoint object.
