commit 5efc5e9fae745e816f70bf4cf8541bc15b7f6872
Author: Ewald Hew <address@hidden>
Commit: Ewald Hew <address@hidden>
[psaux] Objects for new interpreter (part 2)
Make the new objects copy over values. They are essentially wrapper types
for the different decoders/builders.
* include/freetype/internal/psaux.h: Update declarations.
Add is_t1 flag to PS_Builder.
* src/psaux/psdecode.h, src/psaux/psobjs.h: Update declarations.
* src/psaux/psdecode.c, src/psaux/psobjs.c: Implement copy with two modes.
* src/psaux/psauxmod.c: Add builder and decoder functions to PSAux service.
