Font configuration/fontconfig examples
Configurations can vary to a degree. Please post Fontconfig configurations with an explanation for why they were done.
brebs' configuration
This is a quest to get all fonts looking beautiful at all sizes, weights, etc., by tweaking the Fontconfig rules for Infinality rendering. The latest version is maintained here -- brebs
Basic config with no hinting for italic or bold and some other tuning

Sharp fonts
It took me a while to find font settings that are sharp and not overly blurred. This font config does exactly that and seems to work fine everywhere. I searched for this because "Chromium" wasn't looking good with no aliasing at all. The below config fixes that as well.
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<match target="font">
<edit name="antialias" mode="assign"><bool>true</bool></edit>
<edit name="hinting" mode="assign"><bool>true</bool></edit>
<edit name="hintstyle" mode="assign"><const>hintfull</const></edit>
<edit name="lcdfilter" mode="assign"><const>lcddefault</const></edit>
<edit name="rgba" mode="assign"><const>rgb</const></edit>
</match>
</fontconfig>
