The working group has deemed that images are better than ascii
223+
art for the spec.
224+
225+
Style guidelines from From Bert:
226+
227+
*Choose one font (Helvetica or Helvetica Narrow)
228+
*Choose three colors (black, white, red)
229+
*Choose two line thicknesses (1px, 3px)
230+
*Choose two line styles (solid, dotted)
231+
*Choose two image sizes (large: as wide as the page, and small: half as
232+
wide)
233+
234+
*If one of us turns out to be a good cartoonist, we can liven up the
235+
pictures a bit with one human or animal figure per picture, and maybe
236+
even one or two free-hand curves, but better not force ourselves here.

244+
245+
Whatever tools are handy and do the job correctly. As to formats,
246+
bitmapped images should be available in PNG and GIF for paletted images
247+
and JPEG for suitable 24bit images; we should also retain a lossless master
248+
image (24bit PNG). If the artwork was generated from a vector format, the
249+
vector master should also be retained.
