[Freetype] FTC_ImageType : definition change

[Jungshik Shin]

Hi,

I realized that the definition of FTC_ImageType(Rec) had changed last
December (between 2.1.5 and 2.1.6). Before the change [1], it was defined
as


  typedef struct  FTC_ImageTypeRec_
    {
      FTC_FontRec  font;
      FT_Int32     flags;

    } FTC_ImageTypeRec;

while after the change it's defined as

   typedef struct  FTC_ImageTypeRec_
       {
         FTC_FaceID   face_id;
         FT_Int       width;
         FT_Int       height;
         FT_Int32     flags;

       } FTC_ImageTypeRec;

 This presents a challenge for programs like Mozilla [2]. We can detect the
freetype version at the configuration time to get it compiled
differently depending on the freetype version, but  what about the run-time
difference?   It'd be nice to know how others worked around this problem
without releasing two binaries (one for freetype 2.1.5 or earlier and
the other for freetype 2.1.6 or later).

 TIA,

 Jungshik
