[freetype2] master dff40d0 2/3: Add T1_CONFIG_OPTION_OLD_ENGINE configuration option. |

branch: master
commit dff40d03dff05734b8bf026716b780688f89e830
Author: Ewald Hew <address@hidden>
Commit: Ewald Hew <address@hidden>
Add T1_CONFIG_OPTION_OLD_ENGINE configuration option.
This controls whether the old Type 1 engine gets compiled into FreeType.
It is disabled by default.
* devel/ftoption.h, include/freetype/config/ftoption.h
(T1_CONFIG_OPTION_OLD_ENGINE): New macro.
* include/freetype/internal/psaux.h (PS_Decoder): Remove unused field.
* include/freetype/internal/psaux.h, src/cid/cidgload.c
(cid_load_glyph), src/psaux/psauxmod.c, src/psaux/psobjs.c
(ps_builder_add_point), src/psaux/t1decode.c
(t1_lookup_glyph_by_stdcharcode, t1_decoder_parse_glyph,
t1operator_seac, t1_decoder_parse_charstrings), src/psaux/t1decode.h,
src/type1/t1gload.c (T1_Parse_Glyph_And_Get_Char_String): Surround
relevant code with macro.
Minor code changes.

Extract width parsing from Type 1 parser.
Duplicate the fast advance width calculations from the old parser.
