Werner Lemberg 392cf22f8a Another adjustment to header locations.
This change is a result of a discussion thread on freetype-devel

  http://lists.nongnu.org/archive/html/freetype-devel/2015-06/msg00041.html

Re-introduce the `freetype2' subdirectory for all FreeType header
files after installation, and rename the `freetype2' subdirectory in
the git repository to `freetype'.

* include/freetype2: Renamed to...
* include/freetype: This.

* CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS,
PRIVATE_HEADERS): Updated.
Update creation of `ftconfig.h'.
Install generated `ftconfig.h'.

* Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated.

* builds/amiga/include/config/ftconfig.h, builds/freetype.mk
(PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work),
builds/unix/freetype2.in: Updated.

* builds/unix/freetype-config.in: Updated.
* builds/unix/configure.raw: Don't check for `rmdir'.
* builds/unix/unix-def.in (DELDIR): Use `rm -rf', which is portable
according to the autoconf info manual.
* builds/unix/install.mk (install, uninstall,
distclean_project_unix): Update and simplify.

* builds/wince/*, builds/windows/*: Updated.

* devel/ft2build.h, include/ft2build.h: Updated.

* include/freetype2/config/ftheader.h,
include/freetype2/internal/ftserv.h,
include/freetype2/internal/internal.h: Update all header file
macros.

* src/tools/chktrcmp.py (TRACE_DEF_FILES): Updated.

* docs/*: Updated.

Werner Lemberg fae3820764 Simplify header file hierarchy.
This large patch changes the header file directory layout from
`include/freetype/...' to `include/...', effectively removing one
level.  Since the file `ft2build.h' is also located in `include'
(and it stays there even after installation), all FreeType header
files are now in a single directory.

Applications that use (a) `freetype-config' or FreeType's
`pkg-config' file to get the include directory for the compiler, and
(b) the documented way for header inclusion like

  #include <ft2build.h>
  #include FT_FREETYPE_H
  ...

don't need any change to the source code.

* include/freetype/*: Move up to...
* include/*: ... this directory.

* builds/amiga/include/freetype/*: Move up to...
* builds/amiga/include/*: ... this directory.

*/*: Essentially do `s@/freetype/@/@' where appropriate.

* CMakeList.txt: Simplify.
* builds/unix/freetype-config.in, builds/unix/freetype2.in: For
`--cflags', return a single directory.
* builds/unix/install.mk (install): No longer try to remove `cache'
and `internal' subdirectories; instead, remove the `freetype'
subdirectory.

David Bevan aecbfe1ba7 [ftstroke] Major revision.
The main problems
-----------------

  o If FT_STROKER_LINEJOIN_BEVEL was specified, unlimited miter
    joins (not bevel joins) were generated.  Indeed, the meanings of
    `miter' and `bevel' were incorrectly reversed (consistently) in
    both the code and comments.

  o The way bevel joins were constructed (whether specified
    explicitly, or created as a result of exceeding the miter limit)
    did not match what is required for stroked text in PostScript or
    PDF.

The main fixes
--------------

  o The behaviour of FT_STROKER_LINEJOIN_BEVEL has been corrected.

  o A new line join style, FT_STROKER_LINEJOIN_MITER_FIXED, has been
    introduced to support PostScript and PDF miter joins.

  o FT_STROKER_LINEJOIN_MITER_VARIABLE has been introduced as an
    alias for FT_STROKER_LINEJOIN_MITER.

Additionally, a variety of stroking errors have been fixed.  These
would cause various artifacts (including points `at infinity'),
especially when stroking poor quality fonts.

See

  http://lists.gnu.org/archive/html/freetype-devel/2011-07/msg00001.html

for example documents.  The FreeType stroker now produces results
very similar to that produced by GhostScript and Distiller for these
fonts.

Other problems
--------------

The following problems have been resolved:

  o Inside corners could be generated incorrectly.  Intersecting the
    inside corner could cause a missing triangular area and other
    effects.

    The intersection point can only be used if the join is between
    two lines and both lines are long enough.  The `optimization'
    condition in `ft_stroker_inside' has been corrected; this
    requires the line length to be passed into various functions and
    stored in `FT_StrokerRec'.

  o Incorrect cubic curves could be generated.  The angle
    calculations in `FT_Stroker_CubicTo' have been corrected to
    handle the case of the curve crossing the +/-PI direction.

  o If the border radius was greater than the radius of curvature of
    a curve, then the negative sector would end up outside (not
    inside) the border.  This situation is now recognized and the
    negative sector is circumnavigated in the opposite direction.
    (If round line joins are being used, this code is disabled
    because the line join will always cover the negative sector.)

  o When a curve is split, the arcs may not join smoothly (especially
    if the curve turns sharply back on itself).  Changes in
    direction between adjacent arcs were not handled.  A round
    corner is now added if the deviation from one arc to the next is
    greater than a suitable threshold.

  o The current direction wasn't retained if a the outline contained
    a zero length lineto or a curve that was determined to be
    `basically a point'.  This could cause a spurious join to be
    added.

  o Cubics with close control points could be mishandled.  All eight
    cases are now distinguished correctly.

Other improvements
------------------

o Borders for cubic curves could be too `flat'.
  FT_SMALL_CUBIC_THRESHOLD has been reduced a little to prevent
  this.

o The handling and use of movable points has been simplified a
  little.

o Various values are now computed only if the results are actually
  needed.

o The directions of the outer and inner borders have been swapped,
  as recommended by Graham Asher.
