2212 * NOTES
2213 * This function behaves differently in Win9x and WinNT.
2214 *
2215 * In WinNT, the DC's world transform is updated as the EMF changes
2216 * the Window/Viewport Extent and Origin or it's world transform.
2217 * The actual Window/Viewport Extent and Origin are left untouched.
2218 *
2219 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2220 * updates the scaling itself but only just before a record that
2221 * writes anything to the DC.
2222 *
2223 * I'm not sure where the data (enum_emh_data) is stored in either
2224 * version. For this implementation, it is stored before the handle
2225 * table, but it could be stored in the DC, in the EMF handle or in
2226 * TLS.
