Comment # 6 on bug 1009924 from Jiri Slaby

Well, after days of debugging, the result is:
* noto fonts are ugly as they are set up by default
* dejavu fonts look really pretty in comparison to noto
* interpreter-version 40 OR hinting other than "none" renders even dejavu
really bad
* all fonts look terrible with subpixel hinting (I reverted from modified
freetype to TW's)

So as a short-term workaround, I set the interpreter to 35 and default fonts to
dejavu. See the attached fonts-config.

I could not make noto fonts to look pretty, though.

BTW noto fonts cannot be uninstalled:
