2248 * NOTES
2249 * This function behaves differently in Win9x and WinNT.
2250 *
2251 * In WinNT, the DC's world transform is updated as the EMF changes
2252 * the Window/Viewport Extent and Origin or its world transform.
2253 * The actual Window/Viewport Extent and Origin are left untouched.
2254 *
2255 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2256 * updates the scaling itself but only just before a record that
2257 * writes anything to the DC.
2258 *
2259 * I'm not sure where the data (enum_emh_data) is stored in either
2260 * version. For this implementation, it is stored before the handle
2261 * table, but it could be stored in the DC, in the EMF handle or in
2262 * TLS.
