[BioC] fontsize in Rgraphviz

[Mark W Kimpel]

Li,

I am outputting to a ps file and viewing in Adobe Illustrator. Here are 
the actual values that are set for fontsize but which are being ignored 
in the output. As a test, I have also set all fontsize to "48" as I know 
this is a common fontsize, it also was ignored.
