Strange label placement on radial svg

[hinz1]

When drawing radial (-r) svg images from newick trees labels get placed too close to tips and get rotated strangely.
I guess it looks kind of OK with the fixed 8px font-size (which is way to small for presentations) but after enlarging the labels it looks awkward. Labels overwrite branches etc.
An example: echo "((Axx,Bxx),Cxx,(Dxx,Exx));" |/usr/local/bin/gotree draw svg -r
So, as a feature request: additional options to manipulate font size for labels, text rotation and text placement would be highly appreciated.
