Summary: MAPPING_FixIsotropic behaves wrong with negativ
                    viewport/window extension
           Product: Wine
           Version: 0.9.5.
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-gdi-(printing)
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

If one uses also negativ viewport/window extension, then MAPPING_FixIsotropic
may behave wrong. A solution would be changing line 40 in mapping.c from

if (xdim > ydim)

to

if (fabs(xdim) > fabs(ydim))
