They are used only Red Hat patches for GTK+/Pango ... but now that the
HintStyle setting has landed in upstream fontconfig, there is no reason
that the Red Hat patches can't be landed into GTK+/Pango.
The settings above are XSETTINGS version of the X resources that
Xft reads normally ... the reason for putting them into XSETTINGS is
that we can do change-on-the-fly updates.
It would be nice to do this at the Xft layer, but there are various
issues that make doing it without toolkit cooperation hard:
- Need for Xft to get the events, and track the XSETTINGS window
- Need to queue redraws and resizes of widget elements
- Need to abandon any caches of open fonts
