Also, instead of turning off the hinting completely, we can change
the hint style.  It's a value from 0 to 3, or constants hintnone,
hintslight, hint medium, hintfull.

Try to put the following instead of the above to ~/.fonts.conf.
The hinting will be enabled a little bit (so you'll see a bit clearer
glyph), but shouldn't be deformed too much.
