Antialiasing is ''not'' an unalloyed good, as Joel, for
example, recognizes in his "Three Wrong Ideas ..."

[DKF]: I'm not sure that I agree with Joel.  But ''bad'' antialiasing isn't worthwhile, I'd agree.

[KPV]: Of course its a matter of taste, but I've never liked antialiased fonts. I find that they seem to have a blurry color 
to them which I find distracting.
