2289 *
2290 * NOTES
2291 * This function behaves differently in Win9x and WinNT.
2292 *
2293 * In WinNT, the DC's world transform is updated as the EMF changes
2294 * the Window/Viewport Extent and Origin or its world transform.
2295 * The actual Window/Viewport Extent and Origin are left untouched.
2296 *
2297 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2298 * updates the scaling itself but only just before a record that
2299 * writes anything to the DC.
2300 *
2301 * I'm not sure where the data (enum_emh_data) is stored in either
2302 * version. For this implementation, it is stored before the handle
2303 * table, but it could be stored in the DC, in the EMF handle or in
2304 * TLS.
