1845 * NOTES
1846 * This function behaves differently in Win9x and WinNT.
1847 *
1848 * In WinNT, the DC's world transform is updated as the EMF changes
1849 * the Window/Viewport Extent and Origin or it's world transform.
1850 * The actual Window/Viewport Extent and Origin are left untouched.
1851 *
1852 * In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
1853 * updates the scaling itself but only just before a record that
1854 * writes anything to the DC.
1855 *
1856 * I'm not sure where the data (enum_emh_data) is stored in either
1857 * version. For this implementation, it is stored before the handle
1858 * table, but it could be stored in the DC, in the EMF handle or in
1859 * TLS.
