bar renderer fillopacity

[jesseenloe]

It does not appear fillopacity is working for the bar renderer

http://multigraph.org/docs/renderers/#bar

<renderer type="bar"> <option name="linecolor" value="0xccc" /> <option name="fillcolor" value="0xfff" /> <option name="hidelines" value="2" /> <option name="barwidth" value="0.65" /> <option name="baroffset" value="-6" /> <option name="barbase" value="0" /> <option name="fillopacity" value="0.5" /> </renderer>
