2307 *

2314 * Ignores rect.
2315 *
2316 * NOTES
2317 * This function behaves differently in Win9x and WinNT.
2318 *
2319 * In WinNT, the DC's world transform is updated as the EMF changes
2320 * the Window/Viewport Extent and Origin or its world transform.
2321 * The actual Window/Viewport Extent and Origin are left untouched.
2322 *
2323 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2324 * updates the scaling itself but only just before a record that
2325 * writes anything to the DC.
2326 *
2327 * I'm not sure where the data (enum_emh_data) is stored in either
2328 * version. For this implementation, it is stored before the handle
2329 * table, but it could be stored in the DC, in the EMF handle or in
2330 * TLS.
