completely meaningless with fixed signatures.
Update all callers.

This ensures good logging output, with all lines having a proper
prefix (if requested).
This is a continuation of a similar patch from 2020-12-02, which
missed some locations.
We no longer have to take care of the 8.3 file name limit; this
allows us (a) to introduce longer, meaningful file names, and (b) to
avoid macro names in `#include' lines altogether since some
compilers (most notably Visual C++) doesn't support this properly.
*/*: Replace
#include FOO_H
with
#include <freetype/foo.h>
or something similar. Also update the documentation.
This monster commit was created by applying Nikhil's scripts
`docconverter.py' and `markify.py' to all C header and source files,
followed up by minor manual clean-up.
No change in functionality, of course.
I used commit f7419907bc6044b9b7057f9789866426c804ba82 from
https://github.com/nikramakrishnan/freetype-docs.git.
Improve the code by 5d3ff05615 ,
issues are found by Behdad Esfahbod and Werner Lemberg.
* src/cache/ftcbasic.c (FTC_ImageCache_Lookup): Replace
a subtraction to check higher bit by a bit operation,
and cpp-conditionalize for appropriate systems. Add better
documentation to the comment.
(FTC_ImageCache_LookupScaler): Ditto.
(FTC_SBitCache_Lookup): Ditto.
(FTC_SBitCache_LookupScaler): Ditto.
* src/cache/ftccache.h (FTC_NodeRec): `FT_Offset' (a.k.a. `size_t')
is a better choice for `hash' to hold a pointer than `FT_PtrDist'
(a.k.a. `ptrdiff_t'), especially since the latter is signed,
causing zillions of signedness warnings. [Note that `hash' was of
type `FT_UInt32' before the change to `FT_PtrDist.]
Update all users.
* src/cache/ftcbasic.c, src/cache/ftccache.c, src/cache/ftccmap.c,
src/cache/ftcglyph.c, src/cache/ftcglyph.h: Updated.
This is essentially a mechanical conversion, adding inclusion of
`FT_INTERNAL_DEBUG_H' where necessary, and providing the macros for
stand-alone compiling modes of the rasterizer modules.
To convert the remaining occurrences of FT_Err_XXX and friends it is
necessary to rewrite the code. Note, however, that it doesn't harm
if some cases are not handled since FT_THROW is a no-op.
Some node comparators (comparing the cache node content and
the properties specified by the query) can flush the cache
node to prevent the cache inflation. The change may
invalidate the pointers to the node obtained before the node
comparison, so the change should be noticed to the caller.
The problem caused by the cache node changing is reported by
Harsha, see Savannah bug #31923.
* src/cache/ftccache.h (FTC_Node_CompareFunc): Add new
argument `FT_Bool* list_changed' to indicate the change of
the cached nodes to the caller.
(FTC_CACHE_LOOKUP_CMP): Watch the change of the cached nodes
by `_list_changed'.
(FTC_CACHE_TRYLOOP_END): Take new macro argument `_list_changed'
and update it when FTC_Manager_FlushN() flushes any nodes.
* src/cache/ftccback.h (ftc_snode_compare): Updated to fit
with new FTC_Node_CompareFunc type. (ftc_gnode_compare): Ditto.
* src/cache/ftcbasic.c: Include FT_INTERNAL_OBJECTS_H to
use TRUE/FALSE macros. (ftc_basic_gnode_compare_faceid):
New argument `FT_Bool* list_changed' to indicate the change
of the cache nodes, anyway, it is always FALSE.
* src/cache/ftccmap.c: Include FT_INTERNAL_OBJECTS_H to
use TRUE/FALSE macros. (ftc_cmap_node_compare):
New argument `FT_Bool* list_changed' to indicate the change
of the cache nodes, anyway, it is always FALSE.
(ftc_cmap_node_remove_faceid): Ditto.
* src/cache/ftccache.c (FTC_Cache_NewNode): Pass a NULL
pointer to FTC_CACHE_TRYLOOP_END(), because the result is
not needed. (FTC_Cache_Lookup): Watch the change of the cache
nodes by `list_changed'. (FTC_Cache_RemoveFaceID): Ditto.
* src/cache/ftcglyph.c: Include FT_INTERNAL_OBJECTS_H to
use TRUE/FALSE macros. (ftc_gnode_compare): New argument
`FT_Bool* list_changed' to indicate the change of the cache
nodes, anyway, it is always FALSE. (FTC_GNode_Compare):
New argument `FT_Bool* list_changed' to be passed to
ftc_gnode_compare().
* src/cache/ftcglyph.h (FTC_GNode_Compare): Ditto.
* src/cache/ftcsbits.c (ftc_snode_compare): New argument
`FT_Bool* list_changed' to indicate the change of the cache
nodes, anyway. It is updated by FTC_CACHE_TRYLOOP().
(FTC_SNode_Compare): New argument `FT_Bool* list_changed'
to be passed to ftc_snode_compare().
* src/cache/ftcsbits.h (FTC_SNode_Compare): Ditto.
On LLP64 platforms (e.g. Win64), FT_ULong (32-bit)
variables are inappropriate to calculate hash values
from the memory address (64-bit). The hash variables
are extended from FT_ULong to FT_PtrDist and new
hashing macro functions are introduced. The hash
values on 16-bit memory platforms are changed, but
ILP32 and LP64 are not changed. The hash value in
the cache subsystem is not reverted to the memory
address, so using signed type FT_PtrDist is safe.
* src/cache/ftccache.h (_FTC_FACE_ID_HASH): New hash
function to replace FTC_FACE_ID_HASH() for portability.
* src/cache/ftcmanag.h (FTC_SCALER_HASH): Replace
FTC_FACE_ID_HASH() by _FTC_FACE_ID_HASH().
* src/cache/ftccmap.c (FTC_CMAP_HASH): Ditto.
* src/cache/ftccache.h (FTC_NodeRec): The type of the
member `hash' is changed from FT_UInt32 to FT_PtrDist.
* src/cache/ftccache.h (FTC_Cache_Lookup): The type of the
argument `hash' is changed from FT_UInt32 to FT_PtrDist.
(FTC_Cache_NewNode): Ditto.
* src/cache/ftccache.c (ftc_cache_add): Ditto.
(FTC_Cache_Lookup): Ditto. (FTC_Cache_NewNode): Ditto.
* src/cache/ftcglyph.h (FTC_GCache_Lookup): Ditto.
* src/cache/ftcglyph.c (FTC_GCache_Lookup): Ditto.
* src/cache/ftcbasic.c (FTC_ImageCache_Lookup): The type
of the internal variable `hash' is changed to FT_PtrDist
from FT_UInt32. (FTC_ImageCache_LookupScaler): Ditto.
(FTC_SBitCache_Lookup): Ditto.
(FTC_SBitCache_LookupScaler): Ditto.
* src/cache/ftccmap.c (FTC_CMapCache_Lookup): Ditto.
* src/cache/ftccache.h (FTC_CACHE_LOOKUP_CMP): Ditto.
Also the type of the internal variable `_idx' is changed to
FT_PtrDist from FT_UInt32 for better pointer calculation.
