Werner Lemberg 8a94b1efd6 [autofit] Redesign the recognition algorithm of strong points. 
In particular, local extrema without horizontal or vertical segments
are better recognized:

  + A                + D
   \                /
    \              /
     \            /
      \          /
       \        + C
        \    /
       B +/

If the distances AB and CD are large, point B wasn't previously
detected as an extremum since the `ft_corner_is_flat' function
`swallowed' BC regardless of its direction, tagging point B as weak.
The next iteration started at B and made `ft_corner_is_flat' swallow
point C, tagging it as weak also, et voilà.

To improve that, another pass gets now performed before calling
`ft_corner_is_flat' to improve the `topology' of an outline: A
sequence of non-horizontal or non-vertical vectors that point into
the same quadrant are handled as a single, large vector.

Additionally, distances of near points are now accumulated, which
makes the auto-hinter handle them as if they were prepended to the
next non-near vector.

This generally improves the auto-hinter's rendering results.

* src/autofit/afhints.h (AF_FLAGS): Remove no longer used flag
`AF_FLAG_NEAR'.

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
    freetype-doc-2.5.3.tar.gz
    ftdoc253.zip

  To view the documentation online, go to

  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!
