However, you will note that unless you have very high screen resolution, you cannot
display proper serifs or even really good letter shapes.  Meanwhile, if you anti-
alias, you can use a gray pixel where a serif is supposed to appear, and the eye
will interpret it as a serif.  Also, by using gray pixels, you can make the eye
perceive finer variations in letter shape, and of course, stroke weight.
