           Summary: wmsparse: dpi value assumed is wrong
           Product: Chameleon
           Version: 2.4
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Core
        AssignedTo: chameleon-dev at lists.maptools.org
        ReportedBy: bartvde at xs4all.nl

In wmsparse the dpi value assumed (72 dpi) is wrong compared to what the OGC
specs say (WMS and SLD). It should be 90.71 dpi (0.28 mm per pixel).

        dMinScale = scaleHintToScaleDenominator( dMinScaleHint, 72 );
        dMaxScale = scaleHintToScaleDenominator( dMaxScaleHint, 72 );

should be:

        dMinScale = scaleHintToScaleDenominator( dMinScaleHint, 90.71 );
        dMaxScale = scaleHintToScaleDenominator( dMaxScaleHint, 90.71 );
