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.

The native SDK on earliest Mac OS X (10.0-10.1) did not have

header file, ECANCELED (introduced in 10.2) in POSIX header
file <errno.h> is checked to detect the system version.

suzuki toshiya 084abf0469 [autofit] Add bluezones for CJK Ideographs.
To remove extremas of vertical strokes of CJK Ideographs at
low resolution and make the top and bottom horizontal stems
aligned, bluezones for CJK Ideographs are calculated from
sample glyphs.  At present, vertical bluezones (bluezones
to align vertical stems) are disabled by default.  For detail, see

Behdad Esfahbod 8c82ec5b17 Always ignore global advance.
This makes FT_LOAD_IGNORE_GLOBAL_ADVANCE_WIDTH redundant,
deprecated, and ignored.  The new behavior is what every major user
of FreeType has been requesting.  Global advance is broken in many
CJK fonts.  Just ignoring it by default makes most sense.

Kan-Ru Chen 21b1a0de7c Fix reading of signed integers from files on 64bit platforms.
Previously, signed integers were converted to unsigned integers, but
this can fail because of sign extension.  For example, 0xa344a1eb
becomes 0xffffffffa344a1eb.

We now do the reverse which is always correct because the integer
size is the same during the cast from unsigned to signed.

Old GNU binutils could not accept the reduced syntax
`orr %0, %2, lsl #16'.  Un-omitted syntax like RVCT,
`orr %0, %0, %2, lsl #16' is better.  Reported by
Johnson Y. Yan.  The bug report by Qt developers is
considered too.

suzuki toshiya b8ca6de365 Fix Savannah bug #30373.
Too serious check of errors by `FT_CMap_New' since 2010-07-04
is fixed. Reported by Tor Andersson.

* include/freetype/fterrdef.h
(PSnames_Err_No_Unicode_Glyph_Name): New error code to
indicate the Unicode charmap synthesis failed because
no Unicode glyph name is found.

* src/psnames/psmodule.c (ps_unicodes_init): Return
PSnames_Err_No_Unicode_Glyph_Name when no Unicode glyph name
is found in the font.
* src/cff/cffcmap.c (cff_cmap_unicode_init): Return
CFF_Err_No_Unicode_Glyph_Name when no SID is available.

* src/type1/t1objs.c (T1_Face_Init): Proceed if `FT_CMap_New'
is failed by the lack of Unicode glyph name.
* src/type42/t42objs.c (T42_Face_Init): Ditto.
* src/cff/cffobjs.c (cff_face_init): Ditto.

Eugene A. Shatokhin b33b856a27 Fix Savannah bug #27648.

Fix comment typo.

suzuki toshiya 0ae3271814 Restrict the number of the charmaps in a rogue-compatible mode.
Fix for Savannah bug #30059.

* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Replace `16' the
minimum character code passed by a legacy rogue client by...
* include/freetype/config/ftoption.h (FT_MAX_CHARMAP_CACHEABLE):
This.  It is undefined when FT_CONFIG_OPTION_OLD_INTERNALS is
undefined (thus the rogue client compatibility is not required).

* src/cff/cffobjs.c (cff_face_init): Abort the automatic
selection or synthesis of Unicode cmap subtable when the charmap
index exceeds FT_MAX_CHARMAP_CACHEABLE.
* src/sfnt/ttcmap.c (tt_face_build_cmaps): Issue error message
when the charmap index exceeds FT_MAX_CHARMAP_CACHEABLE.

* src/base/ftobjs.c (find_unicode_charmap): When Unicode charmap
is found after FT_MAX_CHARMAP_CACHEABLE, ignore it and search
earlier one.
(find_variant_selector_charmap): When UVS charmap is found after
FT_MAX_CHARMAP_CACHEABLE, ignore it and search earlier one.
(FT_Select_Charmap): When a charmap matching with requested
encoding but after FT_MAX_CHARMAP_CACHEABLE, ignore and search
earlier one.
(FT_Set_Charmap): When a charmap matching with requested
charmap but after FT_MAX_CHARMAP_CACHEABLE, ignore and search
earlier one.
(FT_Get_Charmap_Index): When a requested charmap is found
after FT_MAX_CHARMAP_CACHEABLE, return the inverted charmap
index.

(ft_pfr_check): Check `face'.
