CHANGES BETWEEN 2.11.0 and 2.11.1

I. IMPORTANT CHANGES

  - Some  fields  in  the  `CID_FaceDictRec`, `CID_FaceInfoRec`, and
    `FT_Data` structures  have been changed  from signed to unsigned
    type,  which  better reflects  the actual usage.  It is also  an
    additional means to protect against malformed input.

II. MISCELLANEOUS

  - Cmake support  has been  further improved.   To do  that various
    backward-incompatible  changes were  necessary; please  see file
    `CMakeLists.txt` for more details.

  - Since version  2.11.0, a  C99 compiler  is necessary  to compile
    FreeType.

  - The experimental  'COLR' v1 API  has been updated to  the latest
    OpenType standard 1.9.

  - The `apinames` tool got a new  option `-wV` to output an OpenVMS
    Linker Option File.

  - VMS support was updated.

  - MS Visual Studio support was added to build the demo programs.
