2000 * This function behaves differently in Win9x and WinNT.
2001 *
2002 * In WinNT, the DC's world transform is updated as the EMF changes
2003 * the Window/Viewport Extent and Origin or it's world transform.
2004 * The actual Window/Viewport Extent and Origin are left untouched.
2005 *
2006 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2007 * updates the scaling itself but only just before a record that
2008 * writes anything to the DC.
2009 *
2010 * I'm not sure where the data (enum_emh_data) is stored in either
2011 * version. For this implementation, it is stored before the handle
2012 * table, but it could be stored in the DC, in the EMF handle or in
2013 * TLS.
