2224 * NOTES
2225 * This function behaves differently in Win9x and WinNT.
2226 *
2227 * In WinNT, the DC's world transform is updated as the EMF changes
2228 * the Window/Viewport Extent and Origin or it's world transform.
2229 * The actual Window/Viewport Extent and Origin are left untouched.
2230 *
2231 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2232 * updates the scaling itself but only just before a record that
2233 * writes anything to the DC.
2234 *
2235 * I'm not sure where the data (enum_emh_data) is stored in either
2236 * version. For this implementation, it is stored before the handle
2237 * table, but it could be stored in the DC, in the EMF handle or in
2238 * TLS.
