Or at least tell the user to enable USE=auto-hinter for freetype. The reason behind this suggestion is the fact that >=webkit-gtk-2.8.0 ignores fontconfig settings for web-fonts and instead uses the autohinter. Without enabled auto-hinter web-fonts are unhinted and look really bad.
Actually, there is no webkit-gtk-2.8 in the overlay that I can see.
Yes, I know. Should have mentioned that it is not available yet despite in my local overlay ;) But the general issue still is true: webkit-gtk-2.8 and later need the freetype autohinter to be available in order to get somewhat better hinted web-fonts. Check google.com/fonts for bad rendering examples ;) Though there is this bug report: https://bugs.gentoo.org/show_bug.cgi?id=547870 Which suggests that the auto-hinter-USE-Flag in freetype is broken/garbage... So probably just adding harfbuzz to freetype made my fonts look less ugly.
