s/usLowerPointSize/usLowerOpticalPointSize/,
s/usUpperPointSize/usUpperOpticalPointSize/.

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.

[truetype] Minor code refactoring.
Two benefits: The allocated FDEF (and IDEF) array gets slightly
smaller, and the `ttdebug' demo program has access to function
numbers without additional costs.
Fortunately, no changes to FontForge are necessary – this is the
only external TrueType debugger I know of, but others may exist and
should check the code accordingly.

[arm] Fix thumb2 inline assembly under LLVM.
When using `ADD' with an immediate operand, the instruction is
actually `ADD Rd, Rn, #<imm12>', that is, the maximum of the
immediate operand cannot exceed 4095. It will fail to compile with
LLVM.
However, in GCC, due to some legacy compatibility considerations,
`ADD.W' will be automatically emitted when the immediate operand is
larger than 4095.

This line was lost in commit 89ca1fd6 (from 2013-06-25). The effect
is to use a previous darkening amount when producing an unhinted,
unscaled outline. This can cause autohint samples in ftgrid and
ftview to be based on darkened CFF outlines instead of unhinted,
undarkened ones.

Fix Savannah bug #39295.
The bug was caused by switching to the initial hintmap (the one in
effect when `moveto' executes) just before drawing the final element
in the charstring. This ensured that the path was closed (in both
Character Space and Device Space). But if the final element was a
curve and if the final hintmap was different enough from the initial
one, then the curve was visibly distorted.
The first part of the fix is to draw the final curve using the final
hintmap as specified by the charstring. This corrects the
distortion but does not ensure closing in Device Space. It may
require the rasterizer to automatically generate an extra closing
line. Depending on the hintmap differences, this line could be from
zero to a couple pixels in length.
The second part of the fix covers the case where the charstring
subpath is closed with an explicit line. We now modify that line's
end point to avoid the distortion.
Some glyphs in the bug report font (TexGyreHeros-Regular) that show
the change are:
25ppem S (98)
24ppem eight (52)
25.5ppem p (85)
Curves at the *end* of a subpath are no longer distorted. However,
some of these glyphs have bad hint substitutions in the middle of a
subpath, and these are not affected.
The patch has been tested with a set of 106 fonts that shipped with
Adobe Creative Suite 4, together with 756 Open Source CFF fonts from
Google Fonts. There are 1.5 million glyphs, of which some 20k are
changed with the fix. A sampling of a few hundred of these changes
have been examined more closely, and the changes look good (or at
least acceptable).
* src/cff/cf2hints.h (CF2_GlyphPathRec): New element `pathIsClosing'
to indicate that we synthesize a closepath line.
* src/cff/cf2hints.c (cf2_glyphpath_init): Updated.
(cf2_glyphpath_pushPrevElem): If closing, use first hint map (for
`lineto' operator) and adjust hint zone.
For synthesized closing lines, use end point in first hint zone.
(cf2_glyphpath_lineTo): Take care of synthesized closing lines. In
particular, shift the detection of zero-length lines from character
space to device space.
(cf2_glyphpath_closeOpenPath): Remove assertion.
Updated.

Better tracing of loaded glyphs.
Previously, the loading of a glyph was traced at level 4, if at all.

[autofit] Make `cjk' module use blue stringsets.
* src/autofit/afcjk.c (AF_CJK_MAX_TEST_CHARACTERS): Removed.
(af_cjk_hani_blue_chars): Removed.
(AF_CJK_BLUE_TYPE_*): Removed.
(af_cjk_metrics_init_blues): Replace AF_CJK_MAX_TEST_CHARACTERS with

`af_blue_stringsets' and `af_blue_strings' (in file `afblue.c').
Instead of three dimensions (as used in the old blue string array)
we now use properties to do the same, saving one loop nesting level.
* src/autofit/afcjk.h: Remove old enumeration values superseded by
the new data in `afblue.h'.
(AF_CJK_IS_TOP_BLUE, AF_CJK_IS_HORIZ_BLUE, AF_CJK_IS_FILLED_BLUE,

[autofit] Introduce data file for blue strings.
The idea is to have a central file which gets processed by a Perl
script to create proper `.c' and `.h' files using templates. There
are two other reasons to do that:
. The data file should be easily readable. We use UTF-8 encoding
which then gets converted to single bytes.
. Since the number of supported scripts will increase soon, the
current usage of blue string arrays is a waste of space. Using
the Perl script it is possible to imitate jagged arrays,
defining enumeration constants as offsets into the arrays.
This commit only adds files without changing any functionality.
* src/autofit/afblue.dat: New data file.
* src/tools/afblue.pl: New Perl script for processing `afblue.dat'.
* src/autofit/afblue.cin, src/autofit/afblue.hin: New template files
for...
* src/autofit/afblue.c, src/autofit/afblue.c: New source files.
To avoid a dependency on Perl, we add them too.

[autofit] Improve handling of `near' points.
Points which are very near to each other are now marked as such.
The `weak' flag is then computed by using the `in' vector of the
first and the `out' vector of the last point of a group of near
points.
For example, this fixes the rendering of glyph `Oslash' in
`Roboto-Thin.ttf'.
* src/autofit/afhints.h (AF_Flags): New value `AF_FLAGS_NEAR'.
* src/autofit/afhints.c (af_glyph_hints_reload): Introduce
the heuristic value `near_limit' to decide whether the current point
is near to the previous one, then set `AF_FLAG_NEAR' accordingly.
Store good `in' vector (of last non-near point) in
`last_good_in_{x,y}' and use it as an argument to
`ft_corner_is_flat' if necessary.

[autofit] Introduce `writing systems'.
This patch adds a new top level to the auto-hinter's script class
hierarchy. It defines `writing systems' which can contain multiple
scripts.
For example, the `latin' writing system (in file `aflatin.c') is
able to support scripts like Latin, Cyrillic, Armenian, etc., which
can be handled similarly.
Scripts are now named using four-letter OpenType tags.
* src/autofit/aftypes.h (AF_ScriptClassRec): Move relevant members
to...
(AF_WritingSystemClassRec): This new structure. It holds pointers
to functions which can be shared among related scripts.

Speed up ARMv7 support.
When building for ARMv7 with thumb2 instructions, the optimized
`FT_MulFix_arm' assembly routine was not being used.
The reason for this is in the `ftconfig.h' header, namely:
- The assembly routine uses the `smull' instruction which is not
available when generating Thumb-1 machine code. It is available
in Thumb-2 mode, though.
- The header was written a long time ago before Thumb-2 became
widely popular (e.g. with Android). So it simply doesn't use the
assembly routine if the `__thumb__' built-in macro is defined.
- When compiling in Thumb-2 mode, the compiler will define both
`__thumb__' and `__thumb2__'.
By checking for `(__thumb2__ || !__thumb__)', we ensure that the
assembly routine is only avoided when generating Thumb-1 code.
Given that this is performance-sensitive function, this improves
`ftbench' as follows on a Galaxy Nexus:
