* src/sfnt/sfdriver (IS_WIN, IS_APPLE): Omit language ID checks.
(get_win_string, get_apple_string): Return NULL when the PostScript
font name characters is not according to specification.
(get_win_string): Make trace output work if the high byte if
non-zero.
(sfnt_get_var_ps_name, sfnt_get_ps_name): Previously we preferred
Win PS name (when there is also an Apple PS name); change this into
a fallback to Apple PS name in case the Win PS name is invalid.
These public API functions(!) were always undocumented and have
escaped all clean-up efforts until now.
* include/freetype/ftoutln.h (FT_Outline_New_Internal,
FT_Outline_Done_Internal): Removed.
* src/base/ftoutln.h (FT_Outline_New_Internal,
FT_Outline_Done_Internal): Merge into...
(FT_Outline_New, FT_Outline_Done): ... these functions.
* docs/README: Updated.
* include/freetype/internal/ftobjs.h (ft_glyphslot_preset_bitmap):
Change return type.
* src/base/ftobjs.c (ft_glyphslot_preset_bitmap): Return the bitmap
size assessment.
* src/raster/ftrend1.c (ft_raster1_render): Use it to refuse the
rendering of enourmous or far-fetched outlines.
* src/smooth/ftsmooth.c (ft_smooth_render_generic): Ditto.
* src/autofit/afhints.h (AF_PointRec) [FT_DEBUG_AUTOFIT]: New arrays
`before' and `after'.
* src/autofit/afhints.c (af_get_strong_edge_index): New auxiliary
function.
(af_glyph_hints_dump_points): Trace `before' and `after' edges.
(af_glyph_hints_align_strong_points) [FT_DEBUG_AUTOFIT]: Set
`before' and `after' information.

* src/psaux/cffdecode.c (cff_decoder_parse_charstrings) <cff_op_roll>
[CFF_CONFIG_OPTION_OLD_ENGINE]: Use modulo for loop count, as
documented in the specification.
Triggered by
https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=10054
* src/truetype/ttgload.c (load_truetype_glyph): Don't use variable
`opened_frame' to trace whether a frame must be closed at the end of
function: This fails because `TT_Vary_Apply_Glyph_Deltas' (which
gets called for space glyphs) uses a frame by itself. Instead,
close the frame after loading the header, then use another frame for
the remaining part of the glyph later on.
Also avoid calling `tt_get_metrics' twice under some circumstances.
* include/freetype/internal/ftcalc.h (ADD_INT64, SUB_INT64,
MUL_INT64, DIV_INT64) [FT_LONG64]: New macros.
* src/base/ftcalc.c (ft_corner_orientation) [FT_LONG64]: Use
`SUB_INT64' and `MUL_INT64'.

* src/truetype/ttgload.c (ON_CURVE_POINT, X_SHORT_VECTOR,
Y_SHORT_VECTOR, REPEAT_FLAG, X_POSITIVE, SAME_X, Y_POSITIVE, SAME_Y,
OVERLAP_SIMPLE): New macros.
(TT_Load_Simple_Glyph): Use new macros to make code more readable.
Remove useless adjustment of `outline->tags' elements.
There is no harm except some umbiguity in broken fonts with duplicate
encodings.
* src/bdf/bdflib.c (_bdf_parse_glyphs): Remove duplicate tracking.
(_bdf_parse_t): Remove large `have' bitfield.
* src/bdf/bdf.h (bdf_font_t): Remove `nmod', `umod', and `modified',
which were set but never used.
* src/bdf/bdflib.c (_bdf_parse_{glyphs,properties}, bdf_load_font):
Updated accordingly.

* src/psaux/cffdecode.c (cff_decoder_parse_charstrings)
<cff_op_random> [CFF_CONFIG_OPTION_OLD_ENGINE]: Use top dict's
`random' field directly if parsing dictionaries.
