   *   Header File Macros

   * @abstract:
   *   Macro definitions used to `#include` specific header files.
   *
   * @description:
   *   The following macros are defined to the name of specific FreeType~2
   *   header files.  They can be used directly in `#include` statements as
   *   in:
   *
   *   ```
   *     #include FT_FREETYPE_H
   *     #include FT_MULTIPLE_MASTERS_H
   *     #include FT_GLYPH_H
   *   ```
   *
   *   There are several reasons why we are now using macros to name public
   *   header files.  The first one is that such macros are not limited to
   *   the infamous 8.3~naming rule required by DOS (and
   *   `FT_MULTIPLE_MASTERS_H` is a lot more meaningful than `ftmm.h`).
   *
   *   The second reason is that it allows for more flexibility in the way
   *   FreeType~2 is installed on a given system.
