 *        EnumEnhMetaFile  (GDI32.@)
 *
 *  Walk an enhanced metafile, calling a user-specified function _EnhMetaFunc_
 *  for each
 *  record. Returns when either every record has been used or
 *  when _EnhMetaFunc_ returns FALSE.
 *
 *
 * RETURNS
 *  TRUE if every record is used, FALSE if any invocation of _EnhMetaFunc_
 *  returns FALSE.
 *
 * BUGS
 *   Ignores rect.
 *
 * NOTES
 *   This function behaves differently in Win9x and WinNT.
 *
 *   In WinNT, the DC's world transform is updated as the EMF changes
 *    the Window/Viewport Extent and Origin or it's world transform.
 *    The actual Window/Viewport Extent and Origin are left untouched.
 *
 *   In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
 *    updates the scaling itself but only just before a record that
 *    writes anything to the DC.
 *
 *   I'm not sure where the data (enum_emh_data) is stored in either
 *    version. For this implementation, it is stored before the handle
 *    table, but it could be stored in the DC, in the EMF handle or in
 *    TLS.
