That's an interesting point. We generate all images at a 3x zoom (3x of the
final target render scale) (with fat lines), then use ImageMagick to reduce the
image to 'normal'. So the transparency of transparent parts will depend on how
ImageMagick processes the alpha channel.

I took a very quick glance, but it looks like the background color (on a Peeron
set listing) is coming through the trans parts. :)
