2213 *
2214 * NOTES
2215 * This function behaves differently in Win9x and WinNT.
2216 *
2217 * In WinNT, the DC's world transform is updated as the EMF changes
2218 * the Window/Viewport Extent and Origin or it's world transform.
2219 * The actual Window/Viewport Extent and Origin are left untouched.
2220 *
2221 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2222 * updates the scaling itself but only just before a record that
2223 * writes anything to the DC.
2224 *
2225 * I'm not sure where the data (enum_emh_data) is stored in either
2226 * version. For this implementation, it is stored before the handle
2227 * table, but it could be stored in the DC, in the EMF handle or in
2228 * TLS.
