[gzip] Support `gzip' encoded header conditionally.
In order to support `gzip' encoded header the call to
`inflateInit2' was modified in commit 6a92b1fadde26477a9179.
However, this code breaks with the outdated internal version
of zlib. This is a temporary fix to conditionally support
`gzip' encoded header whenever a system installation of zlib
is being used.
Problem report in
https://lists.nongnu.org/archive/html/freetype-devel/2020-02/msg00023.html
* src/gzip/ftgzip.c (FT_Gzip_Uncompress): Change the the call to
`inflateInit2' depending on whether the system installation is
being used or the internal copy.

Fix state of `FT_Face' for buggy `gvar' tables (#57923).
By resetting the blend as implemented with this commit fonts with
invalid `gvar' tables may keep calling into `ft_var_load_gvar' from
`tt_set_mm_blend' and failing, but the font was invalid anyway and
we want to keep seeing the failure in `tt_set_mm_blend'.
* src/truetype/ttgxvar.c (ft_var_load_gvar): Calculate length of
offset array once.
Allocate arrays after `FT_FRAME_ENTER' (extra check before
allocating and avoid needing to free array later if error entering
frame).
Always call `FT_FRAME_EXIT'.
Consistently set counts immediately after array initialized.
Reset the blend (particularly `blend->glyphoffsets') on failure.

index and handle negative face indices.

[woff2] Avoid too many calls to `FT_REALLOC'.
We do this by using `totalSfntSize' as an initial reference, and
extending the buffer when required. This reduces rendering time
considerably.
* include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add
`totalSfntSize', rename `total_sfnt_size' to `actual_sfnt_size'.
* src/sfnt/sfwoff2.c (write_buf): Add parameter `dst_size' to keep
track of and update total size of stream.
(WRITE_SFNT_BUF, WRITE_SFNT_BUF_AT): Modify macros accordingly.
(pad4, store_loca, reconstruct_glyf, reconstruct_hmtx,
reconstruct_font): Update parameters to accept `sfnt_size'.
(woff2_open_font): Add variable `sfnt_size'. Use WOFF2 header field
`totalSfntSize' as initial reference (if value makes sense) and
allocate `totalSfntSize' bytes for the sfnt stream. `write_buf'
handles reallocation if and when required. Also resize the stream
to `actual_sfnt_size' after reconstruction.

[woff2] Reconstruct `loca', `hmtx', and swap out stream.
Add necessary functions to reconstruct loca and hmtx tables (the two
remaining tables that can have a transform). `woff2_open_font' is
now capable of loading a woff2 font face. This code may still need
more refining and better memory management.
* include/freetype/internal/wofftypes.h (WOFF2_HeaderRec): Add total
(final) size of sfnt stream.
(WOFF2_InfoRec): Add header checksum value.
* src/sfnt/sfobjs.c (sfnt_open_font): Change `face_instance_index'
parameter to its pointer so its value can be modified by
`woff2_open_font'.
* src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF_AT): New macro to write into
sfnt buffer at given position.
(write_buf): Add parameter `extend_buf' which allows caller to
specify whether buffer should be reallocated before copying data.
(WRITE_SFNT_BUF): Updated.
(pad4, store_loca, reconstruct_htmx): New functions.
(reconstruct_glyf): Calculate loca values and store them.
(reconstruct_font): Call `reconstruct_hmtx', write table record
entries, and calculate table checksums. Also calculate font
checksum and update `checksumAdjustment' entry in head table.
(woff2_open_font): Open stream for sfnt buffer, swap out input
stream and return.
* src/sfnt/sfwoff2.h (woff2_open_font): Modify parameter to accept
pointer to `face_index'.

[woff2] Reconstruct transformed `glyf' table.
Reconstruct `glyf' table if it is transformed in the uncompressed
table stream. Also add necessary structures, macros and functions.
* include/freetype/internal/wofftypes.h (WOFF2_InfoRec,
WOFF2_SubstreamRec, WOFF2_PointRec): New structures.
(WOFF2_TableRec): s/OrigLength/dst_length/.
* src/sfnt/sfwoff2.c (READ_255USHORT, READ_BASE128): Use
`FT_SET_ERROR' to set implicit `error' variable.
(WRITE_SHORT): New macro.
(N_CONTOUR_STREAM, N_POINTS_STREAM, FLAG_STREAM, GLYPH_STREAM,
COMPOSITE_STREAM, BBOX_STREAM, INSTRUCTION_STREAM): New macros to
refer to substreams of the transformed `glyf' tables.
(Read255UShort, ReadBase128): Return errors set by `FT_READ_XXX'
macros.
(with_sign, safe_int_addition): New functions to add sign to values
based on a flag and perform safe addition respectively.
(triplet_decode): Decode variable-length (flag, xCoordinate,
yCoordinate) triplet for a simple glyph. See
https://www.w3.org/TR/WOFF2/#triplet_decoding
(store_points, compute_bbox, composteGlyph_size, reconstruct_glyf):
New functions.
(reconstruct_font): Call `reconstruct_glyf'.
* src/sfnt/sfwoff2.h: Add required constants.
* src/sfnt/woff2tags.h: Move out constants to `sfwoff2.h'.

[woff2] Copy un-transformed tables to sfnt stream.
Copy un-transformed tables to the sfnt stream.
* src/sfnt/sfwoff2.c: (WRITE_SFNT_BUF): New macro.
(write_buf): New function. Extend memory of `dst' buffer and copy
bytes from `src'.
(compute_ULong_sum): New function. Calculate checksum of table.
(reconstruct_font): Change `FT_Byte* sfnt' to `FT_Byte**
sfnt_bytes'. This has been done because we reallocate memory to
`sfnt' multiple times, which may change the pointer value of `sfnt'.
This new pointer must be propogated back to the caller. Same reason
for using a double pointer in `write_buf'.
* src/sfnt/woff2tags.h (WOFF2_DEFAULT_MAX_SIZE): New macro used for
overflow checking.

Change `KnownTags' to a function (`woff2_known_tags'). This avoids
introducing a global constant array. This function returns the
specified index without *any* checks. The caller must ensure that
`index' is within array limits.
* src/sfnt/sfwoff2.c (woff2_open_font): Change `KnownTags[...]'
notation to `woff2_known_tags( ... )'.

[woff2] Uncompress Brotli streams and `face_index' support.
WOFF2 compressed stream is now uncompressed if Brotli is available.
This data is stored in a separate buffer (uncompressed_buf) because
it does not contain direct table data. Certain tables have
transformations applied to them, and they must be reconstructed
before we can write those tables to the SFNT stream.
`face_index' is now being passed as a parameter to
`woff2_open_font'.
* src/sfnt/sfobjs.c (sfnt_open_font): Add parameter
`face_instance_index'.
* src/sfnt/sfwoff2.c (woff2_uncompress): New function.
(woff2_open_font): Call `woff2_uncompress'.

[psaux] (1/2) Handle fonts that use SEAC for ligatures (#56580).
As originally intended, a Type 1 SEAC charstring would be used for
an accented glyph (like `acaron' or `uumlaut'), where the advance
width of the SEAC glyph is the same as that of the `base' glyph
(like `a' or `u'). In this case it is not uncommon for the SEAC
glyph to not use an (H)SBW opcode of its own but to rely on the
value from the base glyph.
However, out-of-spec fonts also use SEAC glyphs for ligatures (like
`oe' or `fi'), and in those cases the overall advance width is
greater than that of the `base' glyph. For this reason we have to
allow that the SEAC glyph can have an (H)SBW value of its own, and
if it has, retain this value, rather than the one from the base
glyph.
* src/psaux/psintrp.c (cf2_interpT2CharString) <cf2_escSEAC>:
Implement it.

[smooth] Restore the span buffering for direct mode only.
The buffer size FT_MAX_GRAY_SPANS is set to 10 spans, which should be
enough to cover the entire scanline for simple glyphs in most cases:
each slightly slanted edge needs up to two spans, plus a filling span
in-between. This is not new, we used to do it before cb4388783cecc.
* src/smooth/ftgrays.c (gray_TWorker): Add `spans' and `num_spans'.
