                 desktop bitmap.


 RETURNS:

  <lSuccess> is TRUE if the function is successful


 DESCRIPTION:

  This Function uses the Windows API function SystemParametersInfo to set
  the new background wallpaper. It does not update the WIN.INI file, so this 
  changes are lost at Windows next startup.
