1983 *
1984 * NOTES
1985 * This function behaves differently in Win9x and WinNT.
1986 *
1987 * In WinNT, the DC's world transform is updated as the EMF changes
1988 * the Window/Viewport Extent and Origin or it's world transform.
1989 * The actual Window/Viewport Extent and Origin are left untouched.
1990 *
1991 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
1992 * updates the scaling itself but only just before a record that
1993 * writes anything to the DC.
1994 *
1995 * I'm not sure where the data (enum_emh_data) is stored in either
1996 * version. For this implementation, it is stored before the handle
1997 * table, but it could be stored in the DC, in the EMF handle or in
1998 * TLS.
