* src/cff/cffgload.c: added a comment regarding "cntrmask" operator

* src/pshinter/pshrec.c: now ignores invalid "hintmask" and "cntrmask"
        operators (instead of returning an error). Glyph 2028 of the CFF font
        "MSung-Light-Acro" couldn't be rendered otherwise (it seems its
        charstring is buggy, though this requires more analysis)..
