2230 * NOTES
2231 * This function behaves differently in Win9x and WinNT.
2232 *
2233 * In WinNT, the DC's world transform is updated as the EMF changes
2234 * the Window/Viewport Extent and Origin or it's world transform.
2235 * The actual Window/Viewport Extent and Origin are left untouched.
2236 *
2237 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2238 * updates the scaling itself but only just before a record that
2239 * writes anything to the DC.
2240 *
2241 * I'm not sure where the data (enum_emh_data) is stored in either
2242 * version. For this implementation, it is stored before the handle
2243 * table, but it could be stored in the DC, in the EMF handle or in
2244 * TLS.
