2219 *
2220 * NOTES
2221 * This function behaves differently in Win9x and WinNT.
2222 *
2223 * In WinNT, the DC's world transform is updated as the EMF changes
2224 * the Window/Viewport Extent and Origin or it's world transform.
2225 * The actual Window/Viewport Extent and Origin are left untouched.
2226 *
2227 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2228 * updates the scaling itself but only just before a record that
2229 * writes anything to the DC.
2230 *
2231 * I'm not sure where the data (enum_emh_data) is stored in either
2232 * version. For this implementation, it is stored before the handle
2233 * table, but it could be stored in the DC, in the EMF handle or in
2234 * TLS.
