          heavy internal modifications to introduce the concept of
          "module services". This is the first step towards a massive
          simplification of the engine's internals, in order to
          get rid of various numbers of hacks.

          Note that this changes will break source & binary compatibility
          for authors of external font drivers.

          Maybe 2.1.6 will be called 2.2.0 after all :-)

/* <Function> */

/* */
/* <Description> */
/* Each driver can provide one or more extensions to the base */
/* FreeType API. These can be used to access format specific */
/* features (e.g., all TrueType/OpenType resources share a common */
/* file structure and common tables which can be accessed through the */
/* `sfnt' interface), or more simply generic ones (e.g., the */
/* `postscript names' interface which can be used to retrieve the */
/* PostScript name of a given glyph index). */
/* */
/* <InOut> */
/* driver :: A handle to a driver object. */
/* */
/* <Input> */
/* t1_interface :: A string designing the interface. Examples are */
/* `sfnt', `post_names', `charmaps', etc. */
/* */
/* <Return> */
/* A typeless pointer to the extension's interface (normally a table */
/* of function pointers). Returns NULL if the requested extension */
/* isn't available (i.e., wasn't compiled in the driver at build */
/* time). */
