Jouk Jansen 9e3c5d7e18 * vms_make.com: Provide separate library compiled with C++.
Some types on OpenVMS x86_64 (for example, `long') have different sizes
depending on whether compiled with either C or C++.  In particular,
X-Windows applications crash if linked with the C++ version.

This patch makes `vms_make.com` create a second version of the FreeType
library compiled with C++ if OpenVMS is running on the x86_64 platform.

Jouk Jansen e8aa5af936 vms_make.com: Add `/warn=noinfo` to `CFLAGS`.
This reduces enormously the informationals while compiling on x86_64 (i.e.,
which `.h` file is inluded form where).

Ben Wagner 85167dbd50 [woff2] Remove sfnt size guess check
In WOFF the `totalSfntSize` must be correct, however in WOFF2 this value
is now just a hint and a conforming implementation must not reject
otherwise valid data if the `totalSfntSize` turns out not to be exact.

* src/sfnt/sfwoff2.c (woff2_open_font): remove check that uncompressed
woff2 data would fit in the sfnt size guess.

Fixes: #1235

Skef Iterum 26a7f0478b [cff] Make blend operator work with floats in private dicts.
The CFF2 blend operator takes N default values and corresponding
sets of deltas and pushes N values specific to a designspace
location.  CFF has a floating point numeric type and the FreeType
blending code was not converting those into its internal 16.16
Fixed type format.

Fixes #1243.

* src/cff/cffparse.c (do_fixed): Handle floating point numbers.
Also fix scaling overflow check for integer-to-fixed conversion.

* src/cff/cffload.c (cff_blend_doBlend): Updated.

Hin-Tak Leung dec2743e6a * src/truetype/ttgload.c (TT_Hint_Glyph): More mostly cosmetic update.
This is a follow-up to commit 49c74ac02, which creates a new local variable
"exec = loader->exec", and shortening a lot of "loader->exec".  This commit
does two more such changes missed in that first commit.

Hugh McMaster 355e919746 [gzip] Don't compile internal zlib development files when using system zlib.
`src/gzip/rules.mk` compiles the internal zlib sources even when using the
zlib development files provided by a host system.  If the internal zlib
development files are not present, FreeType fails to build from source.

This patch ensures the internal zlib development files are only
prerequisites when not using zlib development files on a host system.

* src/gzip/rules.mk (GZIP_DRV_SRCS): Define conditionally.

Ben Wagner 4e1c0e8fba Mark FT_Renderer_Class::raster_class as pointer to const
The `FT_DEFINE_RASTER_FUNCS` macro declares a `const FT_Raster_Funcs`.
The address of the definition is taken and assigned to
`FT_Renderer_Class::raster_class` which is currently `FT_Raster_Funcs*`.
Until recently the `const` was cast away and with the removal of the
cast there are now warnings about dropping this `const`. Instead of
adding back the casts, make `FT_Renderer_Class::raster_class` a pointer
to const, as is done with pointers in other interfaces.

* include/freetype/ftrender.h (FT_Renderer_Class_): mark `raster_class`
as const.

Ben Wagner 7bed7a02f4 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.

Ben Wagner 2fb8eda5d6 */*: 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.

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,

Seigo Nonaka 115e927540 [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.

Werner Lemberg 416d4c25f1 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),

Alexei Podtelezhnikov ad708d70c9 [cache] Revise the dynamic hash table accounting.
Instead of counting entries relative to the middle of the hash table,
this switches to the absolute counter with the full index range mask.
As a result, some calculations become a bit simpler.  The cache resizing
logic stays largely the same.
