Then you can't easily highlight parts of an equation, etc.

The dvips 'color' specials are standardized and used by the default LaTeX color 
package.  There's a huge set of additional specials, of course, but we should 
worry about those as they came up.

I'm indifferent about dvitomp.web vs. dvitomp.ch.  Both Olaf's and my version 
use convenient functions such as "xstrdup" not available in Pascal/Web, however, 
and it doesn't seem worth it to recode it all in Pascal.

But I wish I had known "image" existed, it would have simplified my life 
considerably. :(
