[truetype] Fix linear metrics of GX variation fonts.
When asking for an unhinted non-default variations,
`linearVertAdvance' is currently the value from the `hmtx' table

need sane fallback.

[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.

defining TT_CONFIG_OPTION_GX_VAR_SUPPORT (which brings you CFF2
support without font variation).

variation.
* src/cff/cf2font.h (CF2_Font): Add fields for variation data.
* src/cff/cf2ft.c (cf2_free_instance): Free blend data.

cff_blend_check_vector): New functions.

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

* src/cff/cffload.h: Include `cffparse.h'.

* src/cff/cffobjs.c (cff_face_done): Updated.
* src/cff/cffparse.c: Include `cffload.h'.
(cff_parse_num): Handle internal value 255.

[gzip] Improve building with external zlib (#49673).
Building FreeType with external zlib 1.2.8 makes msvc 14 stop with
the following error.
ftgzip.c
zlib-1.2.8\zlib.h(86): error C2061:
syntax error: identifier 'z_const'
zlib-1.2.8\zlib.h(94): error C2054:
expected '(' to follow 'z_const'
zlib-1.2.8\zlib.h(94): error C2085:
'msg': not in formal parameter list
...
zlib-1.2.8\zlib.h(877): fatal error C1003:
error count exceeds 100; stopping compilation
The error happens because FreeType keeps an own copy of zlib-1.1.4
under `src/gzip'. When building `src/gzip/ftgzip.c' with
FT_CONFIG_OPTION_SYSTEM_ZLIB defined, it uses
#include <zlib.h>
which correctly finds an external `zlib.h', but `zlib.h' itself has
a line
#include "zconf.h"
which makes Visual Studio 2015 find `src/gzip/zconf.h' while
compiling the files in `src/gzip'.
* src/gzip/zconf.h: Rename to...
* src/gzip/ftzconf.h: ... this.
* src/gzip/zlib.h, src/gzip/rules.mk (GZIP_DRV_SRCS): Updated.

makes the test for an embedded bitmap data table succeed for this
format.

Introduce a way of quickly retrieving (embedded) bitmap metrics.
`FT_Load_Glyph' doesn't generate a bitmap for a non-bitmap glyph
until the user calls `FT_Render_Glyph'. However, it always
allocates memory for bitmaps and copies or decodes the contents of a
bitmap glyph, which can be quite slow for PNG data.
* include/freetype/freetype.h (FT_LOAD_BITMAP_METRICS_ONLY): New
macro.
* src/base/ftobjs.c (FT_Load_Glyph): Unset FT_LOAD_RENDER if
FT_LOAD_BITMAP_METRICS_ONLY is used.
* src/sfnt/ttsbit.c (tt_sbit_decoder_alloc_bitmap,
tt_sbit_decoder_load_bitmap): Add argument to control allocation of
the glyph slot.
(tt_sbit_decoder_load_image, tt_sbit_decoder_load_compound,
tt_face_load_sbit_image): Updated.
* src/pcf/pcfdrivr.c (PCF_Glyph_Load): Quickly exit if
`FT_LOAD_BITMAP_METRICS_ONLY' is set.
* src/pfr/pfrsbit.c, src/pfr/pfrsbit.h (pfr_slot_load_bitmap): Add
