  26  *    An array of metafile records
  27  *    A private palette

1847  * NOTES
1848  *   This function behaves differently in Win9x and WinNT.
1849  *
1850  *   In WinNT, the DC's world transform is updated as the EMF changes
1851  *    the Window/Viewport Extent and Origin or it's world transform.
1852  *    The actual Window/Viewport Extent and Origin are left untouched.
1853  *
1854  *   In Win9x, the DC is left untouched, and PlayEnhMetaFileRecord
1855  *    updates the scaling itself but only just before a record that
1856  *    writes anything to the DC.
1857  *
1858  *   I'm not sure where the data (enum_emh_data) is stored in either
1859  *    version. For this implementation, it is stored before the handle
1860  *    table, but it could be stored in the DC, in the EMF handle or in
1861  *    TLS.
