http://bugs.winehq.org/show_bug.cgi?id=17840

Summary: AlphaBlend function in msimg32.dll is not forwarded to
                    gdi32.dll
           Product: Wine
           Version: 1.1.17
          Platform: All
        OS/Version: All
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: gdi32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

AlphaBlend function in msimg32.dll is not forwarded to GdiAlphaBlend in
gdi32.dll.

This stops programs which use AlphaBlend from displaying alpha blended drawing.

There used to be a very simple implementation of AlphaBlend in msimg32.dll
however that was removed when the GdiAlphaBlend method was implemented in what
appears to be a correct fashion.
