* src/psaux/psintrp.c (cf2_doStems): `hsbw' or `sbw' must be the
first operation in a Type 1 charstring.
(cf2_interpT2CharString): Remove unused variables.
<cf2_cmdHMOVETO, cf2_cmdVMOVETO, cf2_cmdRMOVETO>: `hsbw' or `sbw'
must be the first operation in a Type 1 charstring.
<cf2_cmdHSBW, cf2_escSBW>: Fix data access and add correction for
left sidebearing.
* src/psaux/psintrp.c (cf2_interpT2CharString) <c2f_cmdCLOSEPATH>:
Use the right builder function. We can use the `haveWidth' boolean
already present, instead of implementing `parse_state'.
The following Type 1 specific ops have been added (copied from
`t1decode'):
closepath
vstem3
hstem3
seac
sbw
callothersubr
pop
setcurrentpoint
hsbw
The following require a Type 1 mode, because of differences in
specification:
hstem
vstem
vmoveto
callsubr
div
rmoveto
hmoveto
Numbers
The subsequent commits will implement these changes and adapt
accesses of data and objects to the new interpreter.
NOTE: Will not compile in the meantime!
* src/psaux/psintrp.c: Add opcodes to enum.
(cf2_interpT2CharString): Copy relevant code over from
`t1_decoder_parse_charstrings' (in `t1decode.c').
* 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.
