What a pity that the great improvements of the new CFF hinter stay
unused because of defects in components which can't be controlled by
FreeType.
I suggest the following route.
. Given that the current version of the Cantarell fonts has broken
hinting, explicitly disable native CFF hinting for this particular
font family until it gets fixed by the maintainer (basically, it
should be simply re-hinted automatically with FontForge – a matter
of a few minutes' work).
. FontConfig should implement an interface to FreeType's CFF driver
properties `no-stem-darkening' and `darkening-parameters'. Those
two are global options (controlling FT_Library, so to say), not
options local to fonts. In case there are problems I'm open to
suggestions how to improve that on the FreeType side.
. It would be great if users could play with FreeType's default
values of the stem darkening, providing suggestions for better
values in case the rendering system doesn't use linearized
blending and too low gamma values, as discussed in the FreeType
developer's mailing list. It's straightforward then for
distributions to apply a localized patch.
This thread should basically answer all questions:

I really hope that all distribution maintainers read this!
