Title: Added symbols size handling in WMS GetLegendGraphic

This patch handles size for symbols used in PointSymbolizer for the GetLegendGraphic WMS operation allowing:
* symbols bigger than icon size to always being drawn inside the icon box
* have proportional size rendering for symbols used in different rules of the same SLD
* specify a minimum rendered symbol size using the new minSymbolSize LEGEND_OPTIONS key
