So... Currently, FreeType support under Cocoa is some kind of hybrid where the standard QCoreTextFontDatabase uses the FreeType font engine (only) for rendering fonts. The existing fontconfig support seems to take the form of a different FontDataBase which has a comparable relationship with QFontEngineFT.

It might be trivial to replace QCoreTextFontDatabase with QFontconfigDatabase in QCocoaIntegration but that would be a build-time choice.
