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.
