  MoveTo( hDC, nCol, nRow )-> <nlOldPos>
------------------------------------------------------------------------------


 PARAMETER:


  <hDC>        handle that identifies the device context we are going to
               paint to.

  <nCol>       Target column 

  <nRow>       Target row


 RETURNS:

  <nlOldPos> is a long Integer value that stores the old position.
  The nLoWord( <nlOldValue> ) contains the old nCol, and the
  nHiWord( <nLOldValue> ) contains the old nRow.


 DESCRIPTION:

  Some API GDI painting functions like LineTo() require to previously
  determinate the position where to start painting.
  This is done with MoveTo(), it moves the current position to the 
  specified coordinates. 


  EXAMPLE:

     +-------------------------------------------------------------+
     |  /* Get Device context and move to x,y */                   |
     |   hDC := GetDC( oWnd:hWnd )                                 |
     |   MoveTo( hDC, 10, 10 )                                     |
     |                                                             |
     |  /* Create new Pen and draw the line */                     |
     |   LineTo( hDC, 10, 80, CreatePen( PS_SOLID, 1, CLR_BLACK )) |
     |   ReleaseDC( hDC )                                          |
