2292 * NOTES
2293 * This function behaves differently in Win9x and WinNT.
2294 *
2295 * In WinNT, the DC's world transform is updated as the EMF changes
2296 * the Window/Viewport Extent and Origin or its world transform.
2297 * The actual Window/Viewport Extent and Origin are left untouched.
2298 *
2299 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2300 * updates the scaling itself but only just before a record that
2301 * writes anything to the DC.
2302 *
2303 * I'm not sure where the data (enum_emh_data) is stored in either
2304 * version. For this implementation, it is stored before the handle
2305 * table, but it could be stored in the DC, in the EMF handle or in
2306 * TLS.
