2318 *
2319 * NOTES
2320 * This function behaves differently in Win9x and WinNT.
2321 *
2322 * In WinNT, the DC's world transform is updated as the EMF changes
2323 * the Window/Viewport Extent and Origin or its world transform.
2324 * The actual Window/Viewport Extent and Origin are left untouched.
2325 *
2326 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2327 * updates the scaling itself but only just before a record that
2328 * writes anything to the DC.
2329 *
2330 * I'm not sure where the data (enum_emh_data) is stored in either
2331 * version. For this implementation, it is stored before the handle
2332 * table, but it could be stored in the DC, in the EMF handle or in
2333 * TLS.
