Matthew,

The SVG output is a bit off sometimes.  It's a by-product of not really  
using a native SVG module.  We use a very useful module called GD::SVG  
that interprets GD commands into SVG commands.  The results are  
sometimes off.  You might check to see if you have the latest version  
of GD::SVG as the author (Todd Harris, also of Lincoln's lab) may have  
fixed this.  I think I remember telling him something about vertical  
text being wrong.
