Fix some `FT_Fixed` vs. `FT_Long` confusion.
`FT_Fixed` and `FT_Long` are both typedef'ed to be `signed long`. However,
`FT_Fixed` implies that the lower 16 bits are being used to express
fractional values and so these two types should not be confused.
* include/freetype/internal/services/svmm.h (FT_Set_MM_Blend_Func): Use
`FT_Fixed` for `coords`. Users are passing `FT_Fixed` and implementations
are taking `FT_Fixed`.
(FT_Get_MM_Blend_Func): Ditto.
* src/autofit/afcjk.c (af_cjk_metrics_check_digits): Use `FT_Long` for
`advance` and `old_advance`. `advance`'s address is passed as `FT_Long*` to
`af_shaper_get_elem`, which writes the advance in em units (not fixed). The
exact value is not important here as it is only compared to check whether it
has changed.
* src/autofit/aflatin.c (af_latin_metrics_check_digits): Ditto.

*/*: Remove many function pointer casts.
In C it is undefined behavior to call a function through a function pointer
of a different type. This is now detected by the Control Flow Integrity
Sanitizer. All known issues have already been fixed. Prevent any
accidental re-introduction by removing function pointer casts when defining
services. The services will call the service functions through the function
pointers on the service. As a result the functions must have the same type
so there should be no need to cast. Removing the casts allows compilers to
warn about assignment to an incompatible function pointer type.

* docs/formats.txt: Clarify the reference of Type1 GX,
and state that this format is not supported. This
is because the content `TYP1' table is not exactly same
with the Type1 font format specification; no eexec
encryption is used. For detail and concrete examples,

[truetype] Reduce heap allocation of `deltaSet` variation data.
`deltaSet` is an array of packed integers that can be 32 bits, 16 bits, or
8 bits. Before this change, these values were unpacked to 32-bit integers.
However, this can cause big heap allocations, e.g., around 500 KByte for
'NotoSansCJK'. To reduce this amount, store the packed integers and unpack
them just before passing to the calculation. At calculation time, due to
the variable length of region indices, temporary heap allocations are
necessary. This heap allocation is not negligible and visible in `ftbench`
results. So, use stack-allocated arrays for short array calculations.
Fixes #1230.
* include/freetype/internal/ftmmtypes.h (GX_ItemVarDataRec): New fields
`wordDeltaCount` and `longWords`.
* src/truetype/ttgxvar.c (tt_var_load_item_variation_store): Load packed
data.
(tt_var_get_item_delta): Unpack data before applying.

Add new load flag `FT_LOAD_NO_SVG`.
Modern color fonts often contain both an 'SVG' and 'COLR' table. FreeType
always preferred 'SVG' over 'COLR' (this was a design decision), however,
this might not be the right choice for the user. The new flags makes
FreeType ignore the 'SVG' table while loading a glyph.
Fixes #1229.
* include/freetype/freetype.h (FT_LOAD_NO_SVG): New macro.
* src/base/ftobjs.c (FT_Load_Glyph), src/cff/cffgload.c (cff_slot_load),
src/truetype/ttgload.c (TT_Load_Glyph): Use it.

[truetype] Fix PostScript name handling for variation fonts.
A variation font's PostScript name of a named instance is usually different
from the PostScript name of an unnamed instance. However, if a change
between a named instance and an unnamed instance with exactly the same
design axis values happened, it was possible that the PostScript name wasn't
correctly updated.
This commit reorganizes the code to handle this issue within the top-level
API functions, using a new service to trigger recomputation of the
PostScript name.
* include/freetype/internal/services/svmm.h (FT_Construct_PS_Name_Func): New
typedef.
(FT_Service_MultiMasters): New field `construct_ps_name`.
(FT_DEFINE_SERVICE_MULTIMASTERSREC): Updated.

`postscript_name`.

[truetype] Fix deactivation of variation font handling.
According to the documentation, the functions `FT_Set_Named_Instance`,
`FT_Set_MM_Design_Coordinates`, `FT_Set_Var_Design_Coordinates`, and
`FT_Set_Var_Blend_Coordinates` can unset the `FT_FACE_FLAG_VARIATION` flag.
(The same is true for `FT_Set_MM_WeightVector` but this information was
accidentally omitted from the documentation.)
However, if a call of these functions didn't change the axis values this
could fail because internal shortcuts exited too early.
This commit reorganizes the code to handle `FT_FACE_FLAG_VARIATION` in the
top-level API functions, also taking care of the issue at hand.
* src/base/ftmm.c (FT_Set_MM_Design_Coordinates, FT_Set_MM_WeightVector,
FT_Set_Var_Design_Coordinates, FT_Set_MM_Blend_Coordinates,
FT_Set_Var_Blend_Coordinates): Handle `FT_FACE_FLAG_VARIATION`.
* src/truetype/ttgxvar.c (TT_Set_MM_Blend, TT_Set_Var_Design,
TT_Set_Named_Instance) Don't handle `FT_FACE_FLAG_VARIATION`.
* src/type1/t1load.c (T1_Set_MM_Blend, T1_Set_MM_WeightVector,
T1_Set_MM_Design): Ditto.
* src/cff/cffobjs.c (cff_face_init): Use `FT_Set_Named_Instance` instead of
low-level functions.
* src/truetype/ttobjs.c (tt_face_init): Ditto.

* src/cff/cffdrivr/c (cff_get_ps_name): Avoid unnecessary crash.
The situation can happen if `FT_New_Face` (or one of its siblings) is called
with a negative index to get the number of contained faces, followed
immediately by a call to `FT_Get_Postscript_Name`. While this is not a valid
use of the FreeType library there is no need for a crash.
Fixes #1219.

[t1cid] Change the trace messages of the charstrings retrieval errors.
The t1cid driver catches 3 types of errors in
the charstrings retrieval;
A) The invalid FD number, there are 2 subtypes;
A-1) FD number is the maximum number fitting to FDBytes.
A-2) FD number is greater than num_dicts.
B) Declared length is overrunning.
C) Declared length is invalid (its end is before its head).
Considering that some widely distributed fonts
(e.g., "CJKV" book by O'Reilly) have A-1 errors
in the unimplemented glyphs, the trace level for
A-1 is calmed to level 1.
The errors A-2, B, and C would be irregular;
their trace levels are kept at level 0, but
the updated trace messages include the CID number.

[services] FT_Size_Reset_Func to return FT_Error
The `MetricsVariations` `FT_Size_Reset_Func` is currently defined to
return `void`, but the implementations return `FT_Error`. Even though
the pointers passed will be the same at runtime, calling a function
through a pointer of a different type from the original function pointer
type is undefined behavior. This may be caught at runtime by Control
Flow Integrity with something like clang's `cfi-icall`.
Issue: https://crbug.com/1433651
* include/freetype/internal/services/svmetric.h (FT_Size_Reset_Func):
return `FT_Error` instead of `void`.

[truetype] tt_size_reset_height to take FT_Size
The `MetricsVariations` `FT_Size_Reset_Func` is defined to take an
`FT_Size`. Because `tt_size_reset_height` is to be used as such a
function, it must also take an `FT_Size` instead of a `TT_Size`. Even
though the pointers passed will be the same at runtime, calling a
function through a pointer of a different type from the original
function pointer type is undefined behavior. This may be caught at
runtime by Control Flow Integrity with something like clang's
`cfi-icall`.

[sfnt, truetype] Add `size_reset` to `MetricsVariations`.

[truetype] Fix MVAR post-action handling.
```
It is also possible for plain `CFF ` style fonts to contain an `fvar` and
`MVAR` table and use `cff_metrics_adjust`. `tt_size_reset` should only be
called with `TT_Size` and never with `CFF_Size`.
Allow the "metrics-variations" service to specify the correct function (if
any) to reset `FT_Size`s after adjusting metrics.
* src/truetype/ttobjs.c (tt_size_reset): Split off some functionality
into...
(tt_size_reset_height): ... this new function.

`size_reset`.

[cff] Rework the stream limit checks.
The old stream limit checks, before 6986ddac1ece, were good but
pointless for the crafted t2_strings. Checking limits there is
not necessary as they are created to hold all data. By using two
conditions, we can detect the actual crossing of the stream boundary
as appropriate for the stream pointer only. The t2_strings parsing
will not be triggering these checks.

builds/vms/apinames_vms.bash: Fix `unzip` artifact
The problem occured when unpacking a zip file created on OpenVMS on Linux.
While OpenVMS knows many different file formats, Unix only knows stream-LF
and binary. In principle `zip` on Linux should have translated the file to
stream-LF but failed to do so. That caused the file to incorrectly contain
only one line with control-characters.
