The key bit is the -W option -- it draws thick lines. The $scale is the width
of the line, in pixels. For the ldraw/partsref/peeron images, we use -W3 (but
we also set scale to -S3, for a 300% zoom). -Q is supposed to result in
higher-quality, by drawing anti-aliased lines, but I'm not sure how much effect
it has.
