Hi Steve, thanks for letting me know. There is an off-by-one error
and it looks like and easy fix. For future reference, you may want to
consider using GTKAgg as your default GUI. This has the GTK widget
but uses agg for rendering. Agg supports subpixel rendering and so
isn't susceptible to one pixel errors that crop up in GTK in a number
of contexts. At low resolutions, these become particularly
noticeable. Other benefits over the GTK backend are alpha blending,
anti-aliased drawing, and faster image support -

I had a look at http://www.antigrain.com/ and downloaded
agg-2002-05-21.zip.
There's no install document, configure.ac file or Makefile that would
allow me to compile the software. It does not look like this is portable
software that will compile on Linux.
Regards,
Steve
