Instead of a useful font, I get the "symbol not found" boxes. The number of
boxes is equal to the string length.
This leads me to believe that it is having trouble loading the font. I have
looked on the net and been unable to find a sol'n.
Other: I would like to put two $graph objects onto the bigger $gd object,
but the documentation made it look like I needed to use a file handle, and
writing the intermediate .pngs to disk seems like a bit of pointless
redundancy.
Other other: Antialiasing?
Thanks, folks.
