--- Comment #32 from James Cloos <cloos at jhcloos.com> ---
One possible explanation for the difference is that the old fonts may have had
instructions targetting bitmap display and the new targetting grayscale
display.

The older ttf fonts which had very sharp instructed renderings specified
bitmap.
Most of the manually instructed fonts from a decade ago did so.

Most of the newer manually instructed fonts, including newer versions of old
fonts, tend to specify grayscale.  Or to be “optimized for cleartype”.

Either way, they will render differently than those which specify that they are
for bitmap displays.

Bitstream’s Vera is one of the earlier examples of a manually instructed font
family which specifies grayscale.  A comparison of Vera vs current Liberation
may be in order.
