2276 * NOTES
2277 * This function behaves differently in Win9x and WinNT.
2279 * In WinNT, the DC's world transform is updated as the EMF changes
2280 * the Window/Viewport Extent and Origin or its world transform.
2281 * The actual Window/Viewport Extent and Origin are left untouched.
2283 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2284 * updates the scaling itself but only just before a record that
2285 * writes anything to the DC.
2287 * I'm not sure where the data (enum_emh_data) is stored in either
2288 * version. For this implementation, it is stored before the handle
2289 * table, but it could be stored in the DC, in the EMF handle or in
