As I indicated it was a rant. The point being that the legend URL does not
have quite the same expectations as GetLegendGrapics.
You may just end up with a 20x20 copy of our group layer icon for example.
I spend a fair bit of effort on the client side trying to request 20x20
icons often I get back something else (which I then crop) Sounds like that
is a sepereate bug report.
