2232 *
2233 * NOTES
2234 * This function behaves differently in Win9x and WinNT.
2235 *
2236 * In WinNT, the DC's world transform is updated as the EMF changes
2237 * the Window/Viewport Extent and Origin or its world transform.
2238 * The actual Window/Viewport Extent and Origin are left untouched.
2239 *
2240 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2241 * updates the scaling itself but only just before a record that
2242 * writes anything to the DC.
2243 *
2244 * I'm not sure where the data (enum_emh_data) is stored in either
2245 * version. For this implementation, it is stored before the handle
2246 * table, but it could be stored in the DC, in the EMF handle or in
2247 * TLS.
