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
