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: Include FT_INTERNAL_CFF_TYPES_H.
(T1_Parse_Glyph_And_Get_Char_String): 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): New
`cf2_instance' field.
* src/psaux/psdecode.c (ps_decoder_init): Copy `cf2_instance' to
`PS_Decoder'.
* src/psaux/t1decode.c (t1_decoder_done): Add finalization code.
* src/psaux/psft.c (cf2_decoder_parse_charstrings): 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/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.

This is so that we can use the same hinting engine parameters for
Type 1.
* include/freetype/internal/cffotypes.h (CFF_Driver): Rename and
move to...
* include/freetype/internal/psaux.h (PS_Driver): ...here.

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 (ps_builder_init, ps_builder_add_point):
Updated with above changes.
Add some checks for Type 1 data passing through.
* src/psaux/psfont.h (CF2_Font): Add `isT1' flag.
* src/psaux/psfont.c (cf2_font_setup): Skip the variations and blend
code which is not applicable for Type 1.
* src/psaux/psft.c (cf2_decoder_parse_charstrings): Avoid accessing
`decoder->cff' in Type 1 mode.
Copy `is_t1' flag to `CF2_Font'.

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.
(PS_Builder): Add `is_t1' flag.
(PS_Decoder_{Get,Free}_Glyph_Callback): Renamed to...

structs.
* src/psaux/psobjs.c, src/psaux/psobjs.h: Add `PS_Builder'
functions.

`PS_Decoder' initialization functions.
* src/psaux/psaux.c, src/psaux/Jamfile (_sources),
src/psaux/rules.mk (PSAUX_DRV_SRC): 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*: Rename files.
* src/psaux/*: Update includes.
* src/psaux/Jamfile (_sources), src/psaux/rules.mk (PSAUX_DRC_SRC,
PSAUX_DRV_H): Update file references.

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'.

This is so that the CFF functions moved to `psaux' can access the
same structs that they need.
* src/cff/cfftypes.h: Moved to...
* include/freetype/internal/cfftypes.h: ...Here.
* src/cff/cffobjs.h: Moved the struct declarations to...
* include/freetype/internal/cffotypes.h: ... this new file.
* include/freetype/internal/internal.h (FT_INTERNAL_CFF_TYPES_H,
FT_INTERNAL_CFF_OBJECT_TYPES_H): New macros.
* src/cff/cffcmap.h, src/cff/cffdrivr.c, src/cff/cffgload.c,
src/cff/cffgload.h, src/cff/cffload.h, src/cff/cffobjs.c,
src/cff/cffobjs.h, src/cff/cffparse.h, src/psaux/psobjs.h,
include/freetype/internal/psaux.h,
include/freetype/internal/services/svcfftl.h: Update includes.
* src/cff/rules.mk (CFF_DRV_H): Updated.
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: New file, setting up
a `CFFLoad' service.
* include/freetype/internal/ftserv.h (FT_DEFINE_SERVICEDESCREC10,
FT_DEFINE_SERVICEDESCREC): New macros.

This is the first patch of a sequence to move the Type 2 charstring
processing capability from the `cff' module to the `psaux' module.
NOTE: Does not compile!
* src/cff/cf2*: Move these files to...
* src/psaux/cf2*: Here.
* src/cff/Jamfile (_sources), src/cff/rules.mk (CFF_DRV_SRC,
CFF_DRV_H), src/cff/cff.c, src/cff/cffgload.c: Remove file
references.

(FT_Bitmap_LcdFilterFunc, ft_lcd_filter_fir): Move from here...
* include/freetype/ftlcdfil.h (FT_Bitmap_LcdFilterFunc,
ft_lcd_filter_fir): ... to here.
* src/base/ftobjs.c (ft_open_face_internal): NULL-initialize the
per-face filter.
(FT_Face_Properties): Set it.
* src/smooth/ftsmooth.c (ft_smooth_render_generic): Simplify.
* src/base/ftlcdfil.c (ft_lcd_filter_fir, FT_Libary_SetLcdFilter):
Minor.
For GPOS pair positioning format 1 the description of ValueRecords
in the OpenType specification (1.8.2, from today) is wrong – the
offset has to be taken from the parent structure; in this case the
`PairSet' table.
* src/otvalid/otvgpos.c (otv_PairSet_validate): Set `extra3'.
(otv_PairPos_validate): Adjust.
Without this change, clang's AddressSanitizer reports many runtime
errors due to misaligned addresses.
* src/truetype/ttgxvar.c (TT_Get_MM_Var): Use multiples of pointer
size for sub-array offsets into `mmvar'.
* build/windows/vc2010/freetype.vcxproj: Use DynamicLibrary in Debug
and Release configurations.
* include/freetype/config/ftconfig.h (FT_EXPORT, FT_EXPORT_DEF)
[_DLL]: Use Visual C++ extensions.
1. If `FamilyName' is present in the CFF font, use this for
FT_Face's `family_name'.
2. Otherwise, use the face name and chop off any subset prefix.
3. If at this point FT_Face's `family_name' is set, use this
together with the full name to determine the style.
4. Otherwise, use `CIDFontName' as FT_Face's `family_name'.
5. If we don't have a valid style, use "Regular".
Previously, FT_Face's `family_name' entry for pure CFF fontdata
nearly always was the fontname itself, instead of the `FamilyName'
entry in the CFF font (assuming there is one).
* src/cff/cffobjs.c (cff_face_init) [pure_cff]: Implement it.
__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.
