* include/freetype/internal/psaux.h, src/psaux/psobjs.{c,h}:
Rearrange `ps_builder_init' arguments to conventional order.
* src/psaux/psft.c (cf2_decoder_parse_charstrings): Add a check and
notice for `SubFont' in Type 1 mode.
This concludes the changes needed to add Type 1 support.
* src/psaux/psintrp.c: Update includes.
(cf2_interpT2CharString) <cf2_escSEAC>: Implement this similarly to
implied seac for CFF.
* src/psaux/t1decode.c (t1_lookup_glyph_by_stdcharcode_ps): New
function to look up the glyph index.
* src/psaux/psft.c (cf2_getT1SeacComponent,
cf2_freeT1SeacComponent): New functions to get the charstrings for
seac components.
* src/psaux/t1decode.h, src/psaux/psft.h: Update declarations.
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.
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.
* 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: Update 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 (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'.
* 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.
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.
