[postgis-devel] KNN <#> Operator - odd results

[maplabs at light42.com]

Hi All -

  the distances generated by the <#> operator, shown on

      http://download.osgeo.org/postgis/knn_misc/knn_rbox_ansF.png

seemed odd to me.. now I could have made a mistake - but the session is 
transcribed
so it is repeatable... 

  an informal double-check just now gave me  these *actual* distances
(in fake pixel units of the screenshot, blown up twice)

  distance order             pixel distance     
should-be order

    
1                                 
50                      2

    
2                                 
60                      4
