2330 * Walk an enhanced metafile, calling a user-specified function _EnhMetaFunc_
2331 * for each
2332 * record. Returns when either every record has been used or
2333 * when _EnhMetaFunc_ returns FALSE.
2334 *
2335 *
2336 * RETURNS
2337 * TRUE if every record is used, FALSE if any invocation of _EnhMetaFunc_
2338 * returns FALSE.
2339 *
2340 * BUGS
2341 * Ignores rect.
2342 *
2343 * NOTES
2344 * This function behaves differently in Win9x and WinNT.
2345 *
2346 * In WinNT, the DC's world transform is updated as the EMF changes
2347 * the Window/Viewport Extent and Origin or its world transform.
2348 * The actual Window/Viewport Extent and Origin are left untouched.
2349 *
2350 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2351 * updates the scaling itself but only just before a record that
2352 * writes anything to the DC.
2353 *
2354 * I'm not sure where the data (enum_emh_data) is stored in either
2355 * version. For this implementation, it is stored before the handle
2356 * table, but it could be stored in the DC, in the EMF handle or in
2357 * TLS.
