[Chameleon] Scale dependent layers in LegendTemplate

[Dejan Gambin]

Hi,

Unfortunatelly this is not "enough" I think. I found Paul's notes on this
issue that says:

"There can be a problem with scale-dependent-layers ... essentially, 
Chameleon keeps track of which layers are currently 'visible' through 
the legend template mechanism in mapserver.  Layers that are 
out-of-scale are considered off and so the associated checkbox is not 
checked.  When the checkbox is off, Chameleon explicitly sets the layer 
status to off ... so when it does come into scale, the layer doesn't 
come on as it should"

...so something needs to be changed in Chameleon...
