I mean that, in a scanning context, if you see a "line art" setting, it
normally produces a 1bpp result.

When the art in question is something like a woodcut or an ink sketch -
which is what I suspect the line-art settings are more designed for -
aliasing is not a problem in the same way that it is for something
that, like an electronic schematic, is full of lines that really ought
to be aligned with the pixel grid's axes.

giftopnm has been around even longer. :-)

No, it doesn't - but I wasn't claiming GIF support in "all
still-maintained graphics programs", either.  (:-þ back atcha. :)
