Simply put it, an application should never try to access the font
engine's internal structures (since these are bound to change
between releases).

I cannot make any guarantee that the above code will work in
2.1.x or 2.2.x

On the other hand, if you need to access some internal data,
you'd better ask for a specific API on the devel list. There
are chances we'll hear you and provide you with something
useful..

Another way is to provide a patch that implements the new
API you want. Don't be surprised if we happen to modify it
slightly (e.g. Keith Packard's original FT_Get_Next_Char
has been quite modified), but this will greatly speed its
acceptance, and we will continue to support it in later
releases..

So, what do you need to access exactly ? What is it for ?
