Well, commenting out 4 lines of code is not that impressive a task...

By the way, it should be quite safe to install this in the 21.3
release branch (which will certainly not see a complete color
overhaul).  If you take a look at the screen shots at
<URL:http://preview-latex.sf.net>, you will notice the disconcerting
off-color effects that the unpatched Emacs produces (the linguist
screen shots) when not working with fully saturated colors.

If Emacs is devastatingly slow on images and gets terminal palette
starvation in no time at all on paletted display, at least the static
views of non-paletted displays will look nice in screen shots.

People will be glad about the improvement they get, not knowing what
they should rather be getting...
