[Chameleon] current, actual legend

[bartvde at xs4all.nl]

Hi Markus,

if I understand your problem correctly (you want to show only the visible
layers in your legend template), there was a new keyword (layer_visible)
added to the legend template processor of mapscript which would enable you
to do this.

See the following bug report for more info (648):
http://mapserver.gis.umn.edu/bugs/show_bug.cgi?id=648

Best regards,
Bart
