WMS GetLegendGrapics: with LAYERFONTSIZE and ITEMFONTSIZE equal to 0, the labels should not be drawn.

As subject, for the WMS request GetLegendGrapics:
 if I set LAYERFONTSIZE and ITEMFONTSIZE to 0, the labels should not be drawn.

Useful for Qgis Web Client, you can get the graphic of the symbol and put it in the layer tree (in the left panel) without labels, since there is already the layer name in the layer tree.
