* src/cff/cffgload.c (cff_operator_seac): Fix magnitude of 

accent offset.
Update code similarly to the seac support for Type 1 fonts.
(cff_decoder_parse_charstrings) <cff_op_endchar>: Fix magnitude
of accent offset.
Don't hint glyphs twice if seac is emulated.
<cff_op_flex>: Assign correct point tags.
* docs/CHANGES: Updated.

* src/type1/t1parse.c (T1_Get_Private_Dict): Use FT_MEM_MOVE, not
FT_MEM_COPY, for copying the private dict.

* src/type1/t1load.c (parse_subrs): Assign number of subrs only
in first run.
(parse_charstrings): Parse /CharStrings in second run without
assigning values.
(parse_dict): Skip all /CharStrings arrays but the first.  We need
this for non-standard fonts like `Optima' which have different
outlines depending on the resolution.  Note that there is no
guarantee that we get fitting /Subrs and /CharStrings arrays; this
can only be done by a real PS interpreter.

- The descender metrics (face->size->metrics.descender) for WinFNT
bitmap fonts had the wrong sign.
- The (emulated) seac support for CFF fonts was broken.
- The flex operator didn't work for CFF fonts.
