What happens if an app requests GGO_UNHINTED,NONANTIALIASED_QUALITY,
ANTIALIASED_QUALITY,CLEARTYPE_QUALITY and similar flags?  Freetype's
autohinting is far not the same as the bytecode interpreted glyphs, and
Wine has enough problems due to the missing bytecode interpreter already.
Forcing anything the Linux distro developers think or a user sets on their
own is going to lead to all kind of hardly to debug/weird font rendering bugs.
