Werner Lemberg ee5105107b [sfnt] Implement support for `OS/2' table version 5.
See

  http://typedrawers.com/discussion/470/new-microsoft-size-specific-design-selection-mechanism

for the announcement.

* include/freetype/tttables.h (TT_OS2): Add fields
`usLowerPointSize' and `usUpperPointSize'.  Since FreeType returns
this structure only as a pointer through `FT_Get_Sfnt_Table', there
shouldn't be any ABI problems.

* src/sfnt/ttload.c (tt_face_load_os2): Implement it.

* docs/CHANGES: Updated.

Chongyu Zhu 41632b58ef [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.

David Turner b28908860d Optimize FT_MulFix for x86_64 GCC builds.
This patch provides an optimized `FT_MulFix' implementation for
x86_64 machines when FreeType is built with GCC, or compatible
compilers like Clang.

Example:
  bin/ftbench -p -t 5 -s 14 -f 0008 Arial.ttf

Before:

  Load                       4.863 us/op
  Load_Advances (Normal)     4.816 us/op
  Load_Advances (Fast)       0.028 us/op

  Get_Glyph                  0.463 us/op
  Get_CBox                   0.077 us/op
  Get_Char_Index             0.023 us/op

  Get_BBox                   0.302 us/op

After:

  Load                       4.617 us/op
  Load_Advances (Normal)     4.645 us/op
  Load_Advances (Fast)       0.027 us/op

David Turner a5f33eeb8a 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:

Behdad Esfahbod 760d342d37 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.

Werner Lemberg 06474c3e5b [cff] Add a new Type 2 interpreter and hinter.
This work, written by Dave Arnold <darnold@adobe.com> and fully
integrated into FreeType by me, is a donation by Adobe in
collaboration with Google.  It is vastly superior to the old CFF
engine, and it will replace it soon.  Right now, it is still off by
default, and you have to explicitly select it using the new
`hinting-engine' property of the cff driver.

For convenience, (most of) the new files are committed separately.

* include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro.
* include/freetype/ftcffdrv.h: New file to access CFF driver
properties.
* include/freetype/fterrdef.h (FT_Err_Glyph_Too_Big): New error
code.
* include/freetype/internal/fttrace.h: Add `cf2blues', `cf2hints',
and `cf2interp'.

* src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'.
* src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine'
and `no_stem_darkening'.
* src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'.

* src/cff/cff.c: Include new files.
* src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle
`hinting-engine' and `no-stem-darkening' properties (only the Adobe
engine listens to them).
* src/cff/cffgload.c: Include `cf2ft.h'.
(cff_decoder_prepare): Initialize `current_subfont'.
(cff_build_add_point): Handle Adobe engine which uses 16.16
coordinates.
(cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING
separately.
Choose rendering engine based on `hinting_engine' property.
* src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe
engine.
* src/cff/cffobjs.c: Include FT_CFF_DRIVER_H.
(cff_driver_init): Set default property values.

* src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H): Add new files.

* src/cff/cf2*.*: New files, containing the Adobe engine.

  http://openwall.info/wiki/people/solar/software/public-domain-source-code/md5

* include/freetype/internal/fttrace.h: Add `bitmap'.

* src/base/ftobjs.c [FT_DEBUG_LEVEL_TRACE]: Include `md5.c'

(FT_Render_Glyph_Internal) [FT_DEBUG_LEVEL_TRACE]: For tracing,
convert resulting bitmap to a uniform format and compute a checksum.
Use `bitmap' category for the tracing message.

* src/base/rules.mk (BASE_H): Updated.

* docs/LICENSE.TXT: Updated.
