The output quality is substantially improved when using the Freetype
font library. Freetype hinting has previously been disabled in dvipng
(because of substandard output from the Computer Modern font), but
from the 1.8 release onwards, hinting will be enabled in a mode that
prefers shape over contrast (which works well with the Computer Modern
font).

In short, the output quality is visibly better when Freetype is
available than when it isn't.

The release also fixes a few bugs and enhances the internal color
cache for better performance.
