Currently upstream pangocairo changes its backend depending on the
PANGOCAIRO_BACKEND environment variable (set it to 'fc' to use the fontconfig
backend on Windows). fc is configured by config files in <prefix>/etc/fonts.
If you're using GTK3, also check the <prefix>/etc/gtk-3.0/settings.ini
(specifically - gtk-xft-antialias).

%windir%\system32\cttune.exe

Or via the registry ( HKEY_CURRENT_USER\Control Panel\Desktop , the
FontSmoothing* family of keys ).

I don't know whether ClearType has any effect on pangocairo, to be honest.
