I had a closer look at this, and it seems that the specials are
used to implement a reasonably efficient handling of bitmap
graphics in MetaPost. The fshow function is redefined such that
it can output text that encodes a line of a picture. This is
done by the special fonts fmp1, fmp8, fmp24, which correspond to
different colour depths. When the redefined function sees that
one of these pseudo-fonts has been chosen, it interprets the
chars as the data for an image command.
I don't know what I should do about this. I am not really sure
if I like the whole bitmap business in MetaPost. Is it easy to
remedy the problems that these specials cause?
