branch: master
commit ed1d8983f3826124e814145b7556fc8f03ae88df
Author: Nikolaus Waxweiler <address@hidden>
Commit: Werner Lemberg <address@hidden>
[truetype] New implementation of v38 bytecode interpreter [2/3].
This patch actually modifies the bytecode interpreter.
See added comments in `ttinterp.h' for more information on this and
the following commit in the series.
* src/truetype/ttinterp.c (SUBPIXEL_HINTING): Replaced by...
(NO_SUBPIXEL_HINTING, SUBPIXEL_HINTING_INFINALITY,
SUBPIXEL_HINTING_MINIMAL): ...new macros.
(Direct_Move, Direct_Move_X, Direct_Move_Y): Handle backwards
compatibility.
Updated.
(Ins_RS, Ins_FDEF, Ins_ENDF, Ins_CALL, Ins_LOOPCALL, Ins_MD):
Updated.
(Ins_INSTCTRL): Handle native ClearType mode flag.
Updated.
(Ins_FLIPPT, Ins_FLIPRGON, Ins_FLIPRGOFF): Handle backwards
compatibility.
(Move_Zp2_Point): Ditto.
(Ins_SHP): Updated.
(Ins_SHPIX): Handle backwards compatibility.
Updated.
(Ins_MSIRP, Ins_MDAP, Ins_MIAP, Ins_MDRP, Ins_MIRP): Updated.
(Ins_ALIGNRP): Updated.
(Ins_IUP, Ins_DELTAP): Handle backwards compatibility.
Updated.
(Ins_GETINFO): Handle v38 flags.
Updated.
(TT_RunIns): Handle backwards compatibility mode.
Updated.
