The normal action of "-monochrome" is to simply do "-type bilevel".
This has the result of forcing images to be pure black and white.

However it also has a weird side-effect I recently discovered while
reviewing the CLI API interface in that it sets a flag that effects
PDF image reading, forcing it to get a monochrome image from the
ghostscript interface.

It seems a little strange to me, and I would have thought doing
a "-type bilevel" would do the same thing, but evidentially that is not
the case, and I am not certain why!

I have flagged the option for further review, perhaps make it
exactly equivalent to "-type bilevel", which is both a setting and
a operator.
