In this case, it's not the system that's doing it. It has to do with the
fact that GLterm uses OpenGL to render its fonts. From its FAQ:
Why is the text all fuzzy?
A: "Pixels" in the OpenGL coordinate system have a very remote
correspondence to screen pixels. In fact, attempting to have a 1:1
ratio between OpenGL coordinates and screen pixels for texture
boundaries (believe it or not, GLterm is drawing textured rectangles for
each letter it draws) proves to be very hard. For example, ATI and
nVidia have shown completely different results.
As an attempt to help control the problem, you can try using a few key
combinations to nudge the 'convergence' of the texture on the screen.
Note you might not get a perfect result, it depends on the card you
have. A good idea is to use Pixie (in /Developer/Applications) to have
a closer look. The goal when fixing the convergence is to have black
pixels without 'shadows'.
+ Control-Arrow keys will nudge the texture by .005 pixels in the
direction of the arrow. Pressing shift with control will nudge by
.05 pixels instead - ten times as much.
+ Control-Home key will save your settings in the preferences.
Update: The fuzzyness problem has vanished for nVidia cards with MacOSX
10.1.2. It still exists on ATI cards.
