[truetype] Don't trust `maxp's `maxSizeOfInstructions'.
Problem reported by Hin-Tak Leung <htl10@users.sourceforge.net>; see
http://lists.nongnu.org/archive/html/freetype-devel/2013-08/msg00005.html
for details.
* src/base/ftobjs.c (FT_Load_Glyph): Check size of `fpgm' and `prep'
tables also for setting `autohint'.
* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Use code from
`TT_Process_Composite_Glyph' for handling unreliable values of
`maxSizeOfInstructions'.

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.

Implement support for WOFF containers.
We simply synthesize a SFNT from the WOFF, create a memory stream
for the new data, and load the SFNT as usual.

FT_Open_Face: Improve external stream handling.
If the font's `clazz->init_face' function wants to swap to new
stream, handling of whether original stream was external could
result to either memory leak or double free. Mark externality into
face flags before calling `init_face' such that the clazz can handle
external streams properly.

FT_FACE_FLAG_EXTERNAL_STREAM to...

Add support for color embedded bitmaps (eg. color emoji).
A new load flag, FT_LOAD_COLOR, makes FreeType load color
embedded-bitmaps, following this draft specification
https://color-emoji.googlecode.com/git/specification/v1.html
which defines two new SFNT tables, `CBDT' and `CBLC' (named and
modeled after `EBDT' and `EBLC', respectively). The color bitmaps
are stored in the new FT_PIXEL_MODE_BGRA format to represent BGRA
pre-multiplied sRGB images. If PNG support is available, PNG color
images as defined in the same proposed specification are supported
also.
Note that color bitmaps are converted to grayscale if client didn't
ask for color.

Introduce `FT_THROW' macro.
The idea is to replace code like
return FT_Err_Foo_Bar;
or
return CFF_Err_Foo_Bar;
with
return FT_THROW( Foo_Bar );
The FT_THROW macro has two functions:
. It hides the module specific prefix.
. In debug mode, it calls the empty function `FT_Throw' which can
be thus used to set a breakpoint.

[base] Improve trigonometric core.
FreeType used to rely on a 24-step iteration CORDIC algorithm to
calculate trigonometric functions and rotate vectors. It turns out
that once the vector is in the right half-plane, the initial rotation
by 63 degrees is not necessary. The algorithm is perfectly capable
to converge to any angle starting from the second 45 degree rotation.
This patch removes the first rotation and makes it a 23-step CORDIC
algorithm.
* src/base/fttrigon.c (FT_TRIG_SCALE, FT_TRIG_COSCALE): Update macro
values.
(ft_trig_pseudo_rotate, ft_trig_pseudo_polarize): Remove initial

Since the initial commit (ebe85f59) the value of FT_TRIG_SCALE has

were underestimated and rotated vectors were shortened.

[raccess] Modify for PIC build.
Based on the patch provided by Erik Dahlstrom <ed@opera.com>,
http://lists.gnu.org/archive/html/freetype-devel/2012-01/msg00010.html
Also `raccess_guess_table[]' and `raccess_rule_by_darwin_vfs()'
are renamed with `ft_' suffixes.
* src/base/ftbase.h: `raccess_rule_by_darwin_vfs()' is renamed
to `ft_raccess_rule_by_darwin_vfs()'.
* src/base/ftobjs.c: Ditto.
* src/base/ftrfork.c: Declarations of FT_RFork_Rule,
raccess_guess_rec, are moved to...
* include/freetype/internal/ftrfork.h: Here.
* include/freetype/internal/ftrfork.h:
FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END} macros are defined
to replace raccess_guess_table[] in both of PIC and non-PIC
modes.
* src/base/ftrfork.c: raccess_guess_table[] array is rewritten
by FT_RFORK_RULE_ARRAY_{BEGIN,ENTRY,END}.
* src/base/basepic.h (BasePIC): Add `ft_raccess_guess_table'
storage. (FT_RACCESS_GUESS_TABLE_GET): New macro to retrieve
the function pointer from `ft_raccess_guess_table' storage in
`BasePIC' structure.
* src/base/ftrfork.c (FT_Raccess_Guess): Rewritten with
FT_RACCESS_GUESS_TABLE_GET.
(raccess_get_rule_type_from_rule_index): Add `library' as the
first argument to the function, to retrieve the storage of
`ft_raccess_guess_table' from it. Also `raccess_guess_table'
is replaced by FT_RACCESS_GUESS_TABLE_GET.
(ft_raccess_rule_by_darwin_vfs): Ditto.
