I disagree.

Just imagine that a user wants to use the brand-new `foosvg' library
with FreeType.  Using hooks, he can quickly write a few lines of code
to implement the hook callback functions, then registering them.
Done.

On the other hand, writing a new renderer module needs FreeType's
internal header files – which no user code should ever rely on.

I honestly don't know whether it works at all to load a user-compiled
module into FreeType.  AFAICS, the library was not set up to manage
externally compiled modules.
