|1. TeX only accepts letters in symbols, not digits, so trying to use "sf9"
|   as the TeX symbol that refers to the font will result in TeX using the
|   symbol "sf", and screwing up trying to find the font "9=Helvetica".

Oops, you're right. One of the hazards of flipping between different
programming languages.

|2. Some implementations use a 10pt default size for PostScript fonts, but
|   most of those that I have seen use a 1pt (the PostScript default size).
|   On the latter, asking for "scaled 900" will of course give you a 0.9pt
|   size font, which is som small that it is hardly visible.

Correct again. I had forgotten that psdvi uses a base size of 1 pt.
Our filter uses a more reasonable default of 10 pt. To avoid problems,
state the point size explicitly as recommended.
