[freetype2] master 255828c: [autofit] Fix Emscripten crash (patch #9180).

[Werner LEMBERG]

branch: master
commit 255828c8912c580f9ee30a92a757e3b967bc168d
Author: Oleksandr Chekhovskyi <address@hidden>
Commit: Werner Lemberg <address@hidden>

    [autofit] Fix Emscripten crash (patch #9180).
    
    Function calls through pointers must use a matching signature to
    work on Emscripten, since such calls are dispatched through lookup
    tables grouped by signature.
    
    * src/autofit/aftypes.h (AF_WritingSystem_ApplyHintsFunc): Fix
    typedef.
