  many new small, but important, changes there:
  
    - modified the interface of the "sfnt" module. There is now a function
      called "load_format_tag", and another called "load_directory".
  
      The first one is in charge of returning the 4-byte tag located at
      the beginning of a given font file. It understand TrueType collections
      and parses them automatically
  
      The second loads the table directory that is located just after
      the format tag.
  
      This is useful, because the "SFNT" storage scheme can be used by
      several distinct formats, each with its own format tag.
  
      The TrueType driver now checks the format tag in "src/truetype/ttobjs.c"
  
    - made some changes to "src/shared/t1types.h" to clearly separate the
      Type 1 font content from the rest of the T1_Face structure. This
      will be useful when adding the CFF/Type2 driver that will be able
      to reuse the "T1_Font" structure within a "TT_Font" one (which
      really describes a SFNT-based font file).
  
      Some changes in "src/type1" were thus performed to reflect this.
      Note that the current type1 driver will be discontinued in a
      distant future. More on this later..
