Synthesize a SubFont object for Type 1 fonts. This is used in the interpreter
to access Private dict data, which are stored in different places for Type 1
and CFF. This allows the same data to be used in either mode.
* src/psaux/psobjs.c (t1_make_subfont): New procedure to copy required values
to a dummy CFF_SubFont object. This is similar to cff_make_private_dict.
* src/psaux/psobjs.h: Add the new declaration.
* include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Ditto.
Add this to the PSAux Service for future use with CID fonts.
* src/type1/t1gload.c: Add the call.
Move CF2_Font instance to PS_Decoder. This is the context for the interpreter
and since it is currently stored in CFF_Font, is unavailable in Type 1 mode.
* include/freetype/internal/psaux.h (T1_Decoder, PS_Decoder): Add the
cf2_instance field.
* src/psaux/psdecode.c (ps_decoder_init): Copy cf2_instance to PS_Decoder.
Remove unused line.
* src/psaux/t1decode.c (t1_decoder_done): Add finalization code.
* src/psaux/psft.c: Update accesses.
Add the callback and some conditionals to switch between the two
engines.
* include/freetype/internal/psaux.h (T1_Decoder_FuncsRec): Change
function declarations.
* src/psaux/psauxmod.c: Register the callbacks.
* src/psaux/psobjs.c: Add conditionals for number conversion.
* src/type1/t1gload.c: Add code to choose which renderer to use.
* src/cid/cidgload.c: Update call.
* src/base/ftobjs.c, src/psaux/psobjs.c, src/type1/t1gload.c: Update
includes.
Use the previously changed PS_Driver in type1 module to store hinting
engine configuration.
* include/freetype/ftt1drv.h: New file.
Duplicate and rename config options from CFF.
* include/freetype/config/ftheader.h: Define the new file.
* src/type1/t1driver.c: Update declaration.
* src/type1/t1objs.c (T1_Driver_Init): Added.
This is so that we can use the same hinting engine parameters for Type 1.
* include/freetype/internal/cffotypes.h (CFF_Driver): Renamed to PS_Driver...
* include/freetype/internal/psaux.h: ...and moved to here.
* src/cff/cffdrivr.c, src/cff/cffgload.c, src/cff/cffload.c, src/cff/cffobjs.c,
src/cff/cffobjs.h, src/psaux/psft.c, src/psaux/psobjs.c: Updated references.
Make some fields more generic, so that we can access them the same way
regardless of Type 1 or CFF.
* include/freetype/internal/psaux.h (PS_Builder): Change TT_Face to FT_Face.
Remove unused fields.
* src/psaux/psft.c: Update all accesses of PS_Builder.face.
Add some asserts to guard against casting T1_Face as TT_Face.
* src/type1/t1objs.h (T1_GlyphSlot): Reorder fields to follow CFF_GlyphSlot,
so that we can pretend they are the same in the interpreter.
* src/psaux/psobjs.c: Updated with above changes.
Add some checks for Type 1 data passing through.
* src/psaux/psfont.h: Add isT1 flag to CF2_Font.
* src/psaux/psfont.c: Skip the variations and blend code which is not
applicable for Type 1.
* src/psaux/psft.c: Avoid accessing decoder->cff in Type 1 mode.
Copy is_t1 flag to CF2_Font.
* include/freetype/internal/psaux.h, src/psaux/psauxmod.c: Fix switching
between new and old engines.
* src/cff/cffgload.c, src/cff/cffparse.c: Update calls.
* src/psaux/psblues.c, src/psaux/psfont.c, src/psaux/psfont.h,
src/psaux/psft.c, src/psaux/psft.h, src/psaux/psintrp.c: Update all
to use new objects.
Make the new objects copy over values. They are essentially wrapper types
for the different decoders/builders.
* include/freetype/internal/psaux.h: Update declarations.
Add is_t1 flag to PS_Builder.
* src/psaux/psdecode.h, src/psaux/psobjs.h: Update declarations.

Introduce PS_Decoder and PS_Builder which include all fields from either
Type 1 or CFF decoders/builders.
* include/freetype/internal/psaux.h: Added new structs.
* src/psaux/psobjs.c, src/psaux/psobjs.h: Added PS_Builder functions.
* src/psaux/psdecode.c, src/psaux/psdecode.h: New file to hold decoder
initialization functions.
* src/psaux/psaux.c, src/psaux/Jamfile, src/psaux/rules.mk: Updated.
Replace the `cf2' file name prefix with `ps' as the Adobe engine will be
used for both PostScript Types 1 and 2 (CFF) instead of just CFF.
s/cf2/ps/ for all following.
* src/psaux/cf2*: Renamed files.
* src/psaux/*: Update includes.
* src/psaux/Jamfile, src/psaux/rules.mk: Updated file references.
Use MultiMasters service in psaux instead of a call to cff.
The project builds if CFF_CONFIG_OPTION_OLD_ENGINE is not defined.
* src/psaux/cf2ft.c: Update includes.
(cf2_getNormalizedVector): Use mm->get_var_blend instead of cff_get_var_blend.
NOTE: Does not compile!
Minor fix to allow both `cff' and `psaux' to use cff_random.
* src/cff/cffload.c (cff_random): Moved to...
* src/psaux/psobjs.c: Here.
* src/cff/cffload.h: Move corresponding declaration to src/psaux/psobjs.h.
* include/freetype/internal/psaux.h (PSAux_ServiceRec): Register the function here...
* src/psaux/psauxmod.c: And here.

NOTE: Does not compile!

structs that they need.

* include/freetype/internal/cfftypes.h: Here.
* src/cff/cffobjs.h: Moved the struct declarations to...

include/freetype/internal/psaux.h,
include/freetype/internal/services/svcfftl.h: Update includes.

NOTE: Does not compile!
This is to allow CFF functions moved to `psaux' to call functions declared in src/cff/cffload.h.
* include/freetype/internal/services/svcfftl.h: Create new FT_Service_CFFLoad service.

* src/psaux/Jamfile, src/psaux/rules.mk, src/psaux/psaux.c, : Added file references.
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.
We now use a separate preprocessor macro to handle both definition
and declaration of the glyph name arrays.
* src/psnames/psmodule.c (DEFINE_PS_TABLE_DATA): New macro.
* src/tools/glnames.py (StringTable::dump,
StringTable::dump_sublist): Use `DEFINE_PS_TABLE_DATA'.
(dump_encoding): Ditto.
(main): Use `wb' mode for writing the output file, which works on
Windows also.
* src/psnames/pstables.h: Regenerated.
This is a new technology for LCD-optimized rendering. It capitalizes
on the fact that each color channel grid is shifted by a third of a
pixel. Therefore it is logical to render 3 separate monochrome
bitmaps shifting the outline by 1/3 pixel, and then combine them.
Importantly, the resulting output does not require additional LCD
filtering.
* src/smooth/ftsmooth.c (ft_smooth_render_generic)
[!FT_CONFIG_OPTION_SUBPIXEL_RENDERING]: Implement new LCD-optimized
rendering.
* include/freetype/ftlcdfil.h, include/freetype/freetype.h,
include/freetype/config/ftoption.h, devel/ftoption.h: Updated
documentation.
The reserved `flags' field got a value in OpenType version 1.8.2;
unfortunately, the public `FT_Var_Axis' structure misses the
corresponding element. Since we can't add a new field, we add an
access function.
* src/base/ftmm.c (FT_Get_Var_Axis_Flags): New function.
* include/freetype/ftmm.h (FT_VAR_AXIS_FLAG_HIDDEN): New macro.
Updated.
* src/truetype/ttgxvar.c (TT_Get_MM_Var): Increase allocated memory
of `mmvar' to hold axis flags.
Fill the axis flags array.
* docs/CHANGES: Updated.
Phantom points are now saved outside v40 backwards compatibility
mode. This fixes the jumping glyphs when switching between v35 and
v40 monochrome mode.
* src/truetype/ttgload.c (TT_Hint_Glyph): Fix inversed bool logic.
This fixes weird behavior of instructions that resulted in rendering
differences between v35 and v40 in monochrome mode, e.g., in
`timesbi.ttf'.
* src/truetype/ttinterp.c (Ins_GETINFO)
[TT_SUPPORT_SUBPIXEL_HINTING_MINIMAL]: Check
`subpixel_hinting_lean'.
* 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.
