*/* [FT_CONFIG_OPTION_PIC]: Remove all code guarded by this
preprocessor symbol.
*/*: Replace `XXX_GET' macros (which could be either a function in
PIC mode or an array in non-PIC mode) with `xxx' arrays.
* include/freetype/internal/ftpic.h, src/autofit/afpic.c,
src/autofit/afpic.h, src/base/basepic.c, src/base/basepic.h,

Removed.
The subsetted demo font of the report that exhibits the bug has a
very unusual type 2 cmap for Unicode(!): It contains only two
sub-headers, one for one-byte characters (covering the range 0x20 to
0xFA), and a second one for higher byte 0x01 (just for character
code U+0131).
Before this commit, the iterator wasn't able to correctly handle a
sub-header for higher byte 0x01.
* src/sfnt/ttcmap.c (tt_cmap2_char_next): Fix character increment
for outer loop.
Some static function declarations cause unused function warnings if
certain config options are turned off via `ftoption.h'.
* src/base/ftbase.h, src/base/ftrfork.c, src/sfnt/ttbdf.h,
src/truetype/ttgxvar.h: Add #ifdef guards around these sections.
__builtin_shuffle() was introduced in gcc-4.7. The lowest
gcc to enable vector operation is delayed from 4.6 to 4.7.
* src/sfnt/pngshim.c (premultiply_data): Fix cpp-macro to
enable the vector operation, to change the lowest gcc version
from 4.6 to 4.7.
* src/autofit/afshaper.c: Include FT_ADVANCE_H, to use
FT_Get_Advance() in it.
* src/sfnt/ttcmap.c: Include FT_SERVICE_POSTSCRIPT_CMAPS_H
to use PS_Unicodes in it, also include `ttpost.h' to use
tt_face_get_ps_name() in it.
The first 32bit of standard TrueType variants is 0x00010000,
`OTTO', `ttcf', `true' or `typ1'. 2 marginal dfonts on legacy Mac
OS X, Keyboard.dfont and LastResort.dfont, have the sfnt resources
starting 0xA5 followed by `kbd' or `lst'. Considering the following
data could be parsed as conventional TrueType fonts, the header
checking is updated to allow these tags. It seems that recent Mac
OS X has already switched to normal TTF for these fonts.
See the discussion at
http://u88.n24.queensu.ca/exiftool/forum/index.php?topic=3931.0
* include/freetype/tttags.h (TTAG_0xA5kbd, TTAG_0xA5lst): New header
tags for Keyboard.dfont and LastResort.dfont.
* src/sfnt/sfobjs.c (sfnt_open_font): Accept the sfnt resource
starts with TTAG_0xA5kbd or TTAG_0xA5lst.
* src/truetype/ttobjs.c (tt_face_init): Accept the face with the
format tag is TTAG_0xA5kbd or TTAG_0xA5lst.
* src/sfnt/pngshim.c (premultiply_data): Use vectors instead of
scalars.
(vector_shuffle): New macro to take of a different built-in function
name on clang.
This reduces the overhead of `premultiply_data' by 60%.
* src/sfnt/pngshim.c (premultiply_data): Provide code which uses
gcc's (and clang's) `vector_byte' attribute to process 4 pixels at a
time.
Requested by Behdad.
Modern bitmap-only SFNTs like `NotoColorEmoji.ttf' don't contain
entries in the bitmap strike(s) for empty glyphs. Instead, they
rely that a space glyph gets created from the font's metrics data.
This commit makes FreeType behave accordingly.
* include/freetype/fterrdef.h (FT_Err_Missing_Bitmap): New error
code.
* src/sfnt/ttsbit.c (tt_sbit_decoder_load_image): Change error codes
to make a distinction between a missing bitmap in a composite and a
simple missing bitmap.
* src/truetype/ttgload.c (TT_Load_Glyph): For a missing bitmap (in a
bitmap-only font), synthesize an empty bitmap glyph if metrics are
available.
* src/sfnt/sfobjs.c (sfnt_load_face): The units per EM value has now
(tighter) limits.
* src/truetype/ttgload.c (load_truetype_glyph): The new OpenType
version explicitly allows all negative values for the number of
contours if we have a composite glyph (this is for better backwards
compatibility I guess), but it still recommends value -1.
* src/sfnt/ttkern.c (tt_face_load_kern): Don't check for
cross-stream kerning tables since we reject format 2 tables later
on anyways.
Modify code for limit test...
(tt_face_get_kerning): ... to avoid a limit test here.
* src/autofit/afcjk.c, src/autofit/afindic.c: Include `afcjk.h'
earlier.
* src/sfnt/sfobjs.c (sfnt_init_face): Put `memory' variable into
TT_CONFIG_OPTION_GX_VAR_SUPPORT block.
(sfnt_done_face): Protect some code with
TT_CONFIG_OPTION_GX_VAR_SUPPORT.
* src/sfnt/ttsbit.c (tt_face_load_sbix_image): Remove compiler
warning.
* src/truetype/ttgload.c (TT_Load_Simple_Glyph): Put `tmp' variable
into TT_USE_BYTECODE_INTERPRETER block.
(tt_loader_init): Put `error' variable into
TT_USE_BYTECODE_INTERPRETER block.
* src/base/ftsnames.c: Include FT_INTERNAL_DEBUG_H.
* src/cff/cffobjs.c [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Include
FT_MULTIPLE_MASTERS_H and FT_SERVICE_MULTIPLE_MASTERS_H.
* src/sfnt/sfdriver.c [TT_CONFIG_OPTION_GX_VAR_SUPPORT]: Include
FT_MULTIPLE_MASTERS_H and FT_SERVICE_MULTIPLE_MASTERS_H.
(get_win_string, get_apple_string): Initialize `result'.
Everything is guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT.
* include/freetype/internal/tttypes.h (TT_FaceRec): New fields
`var_postscript_prefix' and `var_postscript_prefix_len'.
* src/sfnt/sfdriver.c: Include FT_TRUETYPE_IDS_H.
(sfnt_is_alphanumeric): New wrapperfunction for `ft_isalnum'.
(get_win_string, get_apple_string): Remove `const' from return
value.
(MAX_VALUE_DESCRIPTOR_LEN, MAX_PS_NAME_LEN): New macros.
(hexdigits): New array.
(sfnt_get_var_ps_name): New function, implementing Adobe TechNote
5902 to construct a PS name for a variation font instance.
(sfnt_get_ps_name): Call `sfnt_get_var_ps_name' for font instances.
* src/sfnt/sfobjs.c (sfnt_done_face): Updated.
* src/truetype/ttgxvar.c (tt_set_mm_blend): Reset
`face->postscript_name' to trigger recalculation for new instance
parameters.
Add 128bit MurmurHash 3 function.
Everything is guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT.
* src/sfnt/sfdriver.c (ROTL32): New macro.
(fmix32, murmur_hash_3_128): New functions.
