[freetype2] master 3a528bb: [truetype] Record the end of IDEFs.

[Werner LEMBERG]

branch: master
commit 3a528bbe5aec292598f655567ac48a06e3d2c137
Author: Hin-Tak Leung <address@hidden>
Commit: Werner Lemberg <address@hidden>

    [truetype] Record the end of IDEFs.
    
    To match the logic in FDEF.  The value of the end is only used for
    bound-checking in `Ins_JMPR', so it may not have been obvious that
    it was not recorded.  Tested (as part of Font Validator 2.0) all the
    fonts on Fedora and did not see any change.
    
    * src/truetype/ttinterp.c (Ins_IDEF): Updated.
