     /* ftglue.c: Glue code for compiling the OpenType code from
      *           FreeType 1 using only the public API of FreeType 2
      *
      * By David Turner, The FreeType Project (www.freetype.org)
      *
      * This code is explicitely put in the public domain
      *
      * ==========================================================================
      *
      * the OpenType parser codes was originally written as an extension to
      * FreeType 1.x. As such, its source code was embedded within the library,
      * and used many internal FreeType functions to deal with memory and
      * stream i/o.
      *
      * When it was &#x27;salvaged&#x27; for Pango and Qt, the code was &quot;ported&quot; to FreeType 2,
      * which basically means that some macro tricks were performed in order to
      * directly access FT2 _internal_ functions.
      *
      * these functions were never part of FT2 public API, and _did_ change between
      * various releases. This created chaos for many users: when they upgraded the
      * FreeType library on their system, they couldn&#x27;t run Gnome anymore since
      * Pango refused to link.
      *
      * Very fortunately, it&#x27;s possible to completely avoid this problem because
      * the FT_StreamRec and FT_MemoryRec structure types, which describe how
      * memory and stream implementations interface with the rest of the font
      * library, have always been part of the public API, and never changed.
      *
      * What we do thus is re-implement, within the OpenType parser, the few
      * functions that depend on them. This only adds one or two kilobytes of
      * code, and ensures that the parser can work with _any_ version
      * of FreeType installed on your system. How sweet... !
      *
      * Note that we assume that Pango doesn&#x27;t use any other internal functions
      * from FreeType. It used to in old versions, but this should no longer
      * be the case. (crossing my fingers).
