2188 * This function behaves differently in Win9x and WinNT.
2189 *
2190 * In WinNT, the DC's world transform is updated as the EMF changes
2191 * the Window/Viewport Extent and Origin or it's world transform.
2192 * The actual Window/Viewport Extent and Origin are left untouched.
2193 *
2194 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
2195 * updates the scaling itself but only just before a record that
2196 * writes anything to the DC.
2197 *
2198 * I'm not sure where the data (enum_emh_data) is stored in either
