Werner Lemberg 86d0ca245a [sdf] Correct handling of empty glyphs.
This is a refinement of commit 7b3ebb9.

* src/sdf/ftsdfrend.c (ft_sdf_render): Goto 'Exit' instead of directly
returning.
(fd_bsdf_render): Ditto, also taking care of setting `FT_GLYPH_OWN_BITMAP`
correctly.

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.

Fixes #1233.

* include/freetype/config/ftstdlib.h (ft_sprintf): Replace with...
(ft_snprintf): This new macro.

* src/autofit/afhints.c (af_print_idx): Add argument to pass the buffer
size.
(af_glyph_hints_dump_points, af_glyph_hints_dump_segments,
af_glyph_hints_dump_edges): Updated.

* src/bdf/bdflib.c (BUFSIZE): New macro.
(bdf_parse_properties_, bdf_parse_start_): Use `ft_snprintf`.

* src/tools/ftrandom/ftrandom.c (do_test): Use `snprintf`.

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.
(tt_var_get_item_delta): Unpack data before applying.

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),
src/truetype/ttgload.c (TT_Load_Glyph): Use it.

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.

* src/cache/ftccache.h (FTC_NODE_TOP_FOR_HASH): Revised with new counter.
* src/cache/ftccache.c (ftc_get_top_node_for_hash): Ditto.
(ftc_cache_resize): Simplify reallocations and stop their zeroing.
(ftc_cache_init): Stop over-allocating but keep zeroing initially.
(FTC_Cache_Clear, FTC_Cache_RemoveFaceID): Updated accordingly.

Werner Lemberg c8a24209d3 [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.

* src/base/ftmm.c (FT_Set_Var_Design_Coordinates,
FT_Set_MM_Blend_Coordinates, FT_Set_Var_Blend_Coordinates): Call
`mm->construct_ps_name` to handle `postscript_name`.

`postscript_name`.

(TT_Set_MM_Blend): Simplify.

Werner Lemberg 6713b1e41a [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.
