[cff] Implement CFF2 support (2/2).
The font variation code. All parts dependent on the GX code in the
`truetype' module are guarded with TT_CONFIG_OPTION_GX_VAR_SUPPORT.
In other words, you can still compile the `cff' module without
defining TT_CONFIG_OPTION_GX_VAR_SUPPORT (which brings you CFF2
support without font variation).
* src/cff/cf2font.c (cf2_font_setup): Add support for font
variation.
* src/cff/cf2font.h (CF2_Font): Add fields for variation data.
* src/cff/cf2ft.c (cf2_free_instance): Free blend data.
(cf2_getVStore, cf2_getNormalizedVector): New functions.
* src/cff/cf2ft.h: Updated.
* src/cff/cf2intrp.c: Include `cffload.h'.
(cf2_cmdRESERVED_15, cf2_cmdRESERVED_16): Replace with...
(cf2_cmdVSINDEX, cf2_cmdBLEND): ... this new enum values.
(cf2_doBlend): New function.
(cf2_interpT2CharString): Handle `vsindex' and `blend' opcodes.
* src/cff/cffload.c (FT_fdot14ToFixed): New macro.
(cff_vstore_done, cff_vstore_load): New functions.
(cff_blend_clear, cff_blend_doBlend, cff_blend_build_vector,
cff_blend_check_vector): New functions.

Handle blend data.
(cff_subfont_load, cff_subfont_done): Updated.
(cff_font_load): Handle CFF2 variation store data.

dictionary values.

(CFF_Private): Add `vsindex' field.
(CFF_SubFont): Add fields for blend data.
(CFF_Font): Add `vstore' field.
* src/truetype/ttgxvar.c (TT_Get_MM_Var): `CFF2' is equal to `gvar',
since glyph variation data is directly embedded.

[cff] Make Adobe CFF engine work correctly on 64bit hosts.
Reported by numerous people on the `freetype-devel' list. Without
this fix, glyphs aren't properly aligned on a common baseline.
On 64bit systems, `FT_Pos' expands to `long int', having a width of
64bit. `CF2_Fixed' expands to `int' which is normally 32bit wide on
64bit hosts also. Wrong casts filled up the blues arrays with
incorrect values. Note that all blues values are accessed with the
