I think you have a fundamental misunderstanding of how fontconfig
works. This library is only used to find a best matching font for a
given set of constraints. Essentially, it returns a string that holds
a font's file name, together with auxiliary information the
application might find useful. However, it is the application's job
then to process this font name with a call to `FT_Open_Face'! In
other words, fontconfig has *zero* control how the application loads
the font. It just provides a suggestion, nothing more.
The `switch hinting on/off' configuration and similar parameters in
fontconfig influence the auxiliary information returned together with
the matching font, nothing more. Again, it's the application's job to
adhere to this data while calling `FT_Open_Face'.
[The situation would be different if fontconfig returned an `FT_Face'
data structure: then you could use this library for system-wide font
configuration.]
