* include/internal/t1types.h (AFM_KernPairRec): Make indices
unsigned.
Update users.
(AFM_FontInfoRec): Make element counters unsigned.
Update users.
* src/psaux/afmparse.h (AFM_ValueRec): Add union member for unsigned
int.
* src/psaux/afmparse.c (afm_parse_track_kern, afm_parse_kern_pairs):
Reject negative values for number of kerning elements.
* src/type1/t1afm.c, src/tools/test_afm.c: Updated.
It's unused after the following commits:
[raster] Allocate render pool for mono rasterizer on the stack.
[raster] Remove 5-level gray AA mode from monochrome rasterizer.
The value of FT_RENDER_POOL_SIZE still serves the purpose it used to
serve, which is, to adjust the pool size. But the pool is now
allocated on the stack on demand.
* src/base/ftobjs.c (FT_New_Library, FT_Done_Library): Implement.
It was off by default and couldn't be turned on at runtime. And the
smooth rasterizer superceded it over ten years ago. No point in
keeping. Comments suggested that it was there for compatibility
with FreeType 1.
550 lines down.
* src/raster/ftraster.c (FT_RASTER_OPTION_ANTI_ALIASING,
RASTER_GRAY_LINES): Remove macros and all associated code.
(black_TWorker): Remove `gray_min_x' and `gray_max_x'.
(black_TRaster): Remove `grays' and `gray_width'.
(Vertical_Sweep_Init, Vertical_Sweep_Span, Vertical_Sweep_Drop,
ft_black_render): Updated.
* src/raster/ftrend1.c (ft_raster1_render): Simplify code.
(ft_raster5_renderer_class): Removed.
=========================
Tag sources with `VER-2-5-4'.
* docs/VERSION.DLL: Update documentation and bump version number to
2.5.4.

* include/freetype/freetype.h (FREETYPE_PATCH): Set to 4.
* builds/unix/configure.raw (version_info): Set to 17:3:11.
* CMakeLists.txt (VERSION_PATCH): Set to 4.
* docs/CHANGES: Updated.
All public FreeType enumeration and flag values are uppercase...
* include/tttables.h (FT_Sfnt_Tag): Implement it. For backwards
compatilibity, retain the old values as macros.
* src/base/ftfstype.c (FT_Get_FSType_Flags), src/sfnt/sfdriver.c
(get_sfnt_table): Updated.
`API functions' are functions tagged with `FT_EXPORT_DEF'.
Besides trivial fixes, the following changes are included, too.
* src/base/ftbdf.c (FT_Get_BDF_Charset_ID, FT_Get_BDF_Property): Set
error code if no service is available.
* src/base/ftinit.c (FT_Done_FreeType): Change return value for
invalid `library' parameter to `Invalid_Library_Handle'.
* src/base/ftobjs.c (FT_New_Size): Change return value for invalid
`asize' parameter to `Invalid_Argument'.
* src/base/ftoutln.c (FT_Outline_Copy): Change return value for
invalid `source' and `target' parameters to `Invalid_Outline'.
(FT_Outline_Done_Internal): Change return value for invalid
`outline' parameter to `Invalid_Outline'.
`FT_MulFix' takes `FT_Long' parameters as defined in `freetype.h',
but several inline implementations of it in `ftcalc.h' take
`FT_Int32' arguments. This is causing compiler warnings on x86-64:
If parameters of type `FT_Fixed' (= `FT_Long') are passed to the
inline implementation of this function, integer values are truncated
from 64bit to 32bit.
* include/internal/ftcalc.h (FT_MulFix) [FT_MULFIX_ASSEMBLER]: Add
casts.
* include/internal/ftcalc.h (FT_HYPOT): Move macro from here...
* include/internal/ftobjs.h: ... to here, next to required `FT_ABS'.
* src/smooth/ftgrays.c (gray_render_cubic): Use it here.
We no longer need an otherwise unused typedef that can cause a gcc
warning.
Problem reported by Alexei.
* src/cff/cffobjs.c (cff_driver_init): Use
`CFF_CONFIG_OPTION_DARKENING_PARAMETER_XXX' macros directly.
(SET_DARKENING_PARAMETERS): Removed.
Compile time tests are now ...
* devel/ftoption.h, include/config/ftoption.h: ... here.
* include/internal/ftcalc.h (FT_HYPOT): Macro to approximate Euclidean
distance with the alpha max plus beta min algorithm.
* src/base/ftcalc.c (ft_corner_is_flat): Use it instead of Taxicab metric.
