[Bug 21949] New: Verbose the d3d vertices processing code

http://bugs.winehq.org/show_bug.cgi?id=21949

Summary: Verbose the d3d vertices processing code
           Product: Wine
           Version: 1.1.40
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P3
         Component: directx-ddraw
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

As of Wine 1.1.40, the vertices processing is still not perfect (See bug
19888). Thus, it may be reasonable to make the output more verbose for
unhandled cases.
Related code is located in:
./dlls/ddraw/executebuffer.c:492
named

ERR("Unhandled vertex processing !\n");

That is definitely not enough in order to debug. A good start is to add the
output of "ci->dwFlags" in there as well. It is surely a minor enhancement, but
it is really annoying to recompile the whole Wine because of a small line.
