Werner Lemberg 98e510ee94 [autofit] Fix Savannah bug #42148. 
The adaptation of the cjk auto-hinter module to blue stringsets in
2013-08-25 had three severe bugs.  Mea culpa.

1. Contrary to the latin auto-hinter, characters for reference and
   overshoot values of a blue zone are specified separately.  Due to
   the screwed-up change it didn't work at all.

2. A boolean comparison was erroneously replaced with a cast,
   causing invalid results with the `^' operator later on.  The
   visual artifact caused by this problem is the topic of the bug
   report.

3. Two flag values were inverted, causing incorrect assignment of
   reference and overshoot values.

* src/autofit/afblue.dat: Fix CJK bluestrings, introducing a new
syntax to have both reference and overshoot characters in a single
string.  This is error #1.
Add extensive comments.

* src/autofit/afblue.hin (AF_BLUE_PROPERTY_CJK_FILL): Removed, no
longer used.
(AF_BLUE_PROPERTY_CJK_TOP, AF_BLUE_PROPERTY_CJK_HORIZ): Fix values.
This is error #3.

* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.

* src/autofit/afcjk.c (af_cjk_metrics_init_blues): Correct error #1.
Use character `|' to separate characters for reference and overshoot
values.
Improve tracing messages, synchronizing them with the latin
auto-hinter.
(af_cjk_hints_compute_blue_edges): Fix value of `is_top_right_blue'.
This is error #2.
(af_cjk_align_linked_edge): Add tracing message.

* src/autofit/afcjk.h (AF_CJK_IS_FILLED_BLUE): Removed, no longer
used.

README 

  FreeType 2.5.3
  ==============

  Homepage: http://www.freetype.org

  FreeType is a freely available software library to render fonts.

  It  is  written  in  C,  designed to  be  small,  efficient,  highly
  customizable, and  portable while capable of  producing high-quality
  output  (glyph  images) of  most  vector  and bitmap  font  formats.

  Please   read   the  docs/CHANGES   file,   it  contains   IMPORTANT
  INFORMATION.

  Read the  files `docs/INSTALL*'  for installation  instructions; see
  the file `docs/LICENSE.TXT' for the available licenses.

  The FreeType 2 API reference is located in `docs/reference'; use the
  file   `ft2-toc.html'   as   the   top  entry   point.    Additional
  documentation is available as a separate package from our sites.  Go
  to

    http://download.savannah.gnu.org/releases/freetype/

  and download one of the following files.

    freetype-doc-2.5.3.tar.bz2

  Mailing Lists
  =============

  The preferred way  of communication with the FreeType  team is using
  e-mail lists.

    general use and discussion:      freetype@nongnu.org
    engine internals, porting, etc.: freetype-devel@nongnu.org
    announcements:                   freetype-announce@nongnu.org

  The lists are moderated; see

    http://www.freetype.org/contact.html

  how to subscribe.


  Bugs
  ====

  Please report bugs  by e-mail to `freetype-devel@nongnu.org'.  Don't
  forget to  send a  detailed explanation of  the problem --  there is
  nothing  worse than  receiving a  terse message  that only  says `it
  doesn't work'.

  Alternatively, you may submit a bug report at

    https://savannah.nongnu.org/bugs/?group=freetype


  Enjoy!
