Hi All,
Please review the patch that has been attached to ticket #1428
http://trac.osgeo.org/mapguide/ticket/1428
This patch modifies LegendPlotUtil to omit rendering empty layer groups (ie.
Layer Groups with no visible layers at the current scale) in a legend image.
The resulting behaviour lines up with the old legend printout behaviour in
MG 6.5.
