            Bug ID: 38471
           Summary: scanline ordering different type assignment
           Product: Wine
           Version: 1.7.41
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: directx-d3d

output.c:216:41: warning: implicit conversion from enumeration type 'enum
      wined3d_scanline_ordering' to different enumeration type
'DXGI_MODE_SCANLINE_ORDER'
      (aka 'enum DXGI_MODE_SCANLINE_ORDER') [-Wenum-conversion]
        desc[i].ScanlineOrdering = mode.scanline_ordering;
                                 ~ ~~~~~^~~~~~~~~~~~~~~~~
----
If we look more carefully then we see that wined3d_scanline_ordering assumes
values from 0 to 2 while DXGI from 0 to 3.
The difference is WINED3D_SCANLINE_ORDERING_INTERLACED    = 2 may correspond to
        DXGI_MODE_SCANLINE_ORDER_UPPER_FIELD_FIRST  = 2,
        DXGI_MODE_SCANLINE_ORDER_LOWER_FIELD_FIRST  = 3,
depends on what?
Usual DXGI_MODE_SCANLINE_ORDER_LOWER_FIELD_FIRST but in this case the
assignment is wrong. 2 != 3
