The most important dependency is on linear blending (or gamma
correction) in the compositing of glyph images onto the screen. The stem
darkening function assumes blending with a gamma close to 1.8. If linear
blending is not used (e.g., gamma 1.0) then black text will appear too
dark. This might be a situation where you'd want to disable stem
darkening. But white text would suffer. It really is important to use
proper blending!

Thanks for the explanation! I just looked up a test of my monitor where
it says that the gamma is somewhere between 2.1 and 2.5 depending on
what you do in the OSD menu. How can I tell the CFF engine about that?

Nikolaus
