[freetype2] master 7aeee3c: Introduce FT_UINT_TO_POINTER macro (#50560).

[Werner LEMBERG]

branch: master
commit 7aeee3c50f2656b65f7dc207aa2020bb1398da98
Author: Werner Lemberg <address@hidden>
Commit: Werner Lemberg <address@hidden>

    Introduce FT_UINT_TO_POINTER macro (#50560).
    
    We have to make a separate case for Windows 64's LLP64 data model.
    
    * builds/unix/ftconfig.in, builds/vms/ftconfig.h,
    include/freetype/config/ftconfig.h (FT_UINT_TO_POINTER): New macro.
    
    * src/truetype/ttgload.c (load_truetype_glyph): Use it.
