[smooth] Faster alternative line renderer.
This implementation renders the entire line segment at once without
subdividing it into scanlines. The main speed improvement comes from
reducing the number of divisions to just two per line segment, which
is a bare minimum to calculate cell coverage in a smooth rasterizer.
Notably, the progression from cell to cell does not itself require any
divisions at all. The speed improvement is more noticeable at larger
sizes.

[sfnt] Better checks for invalid cmaps (2/2) (#46019).
While the current code in `FT_Get_Next_Char' correctly rejects
out-of-bounds glyph indices, it can be extremely slow for malformed
cmaps that use 32bit values. This commit tries to improve that.
* src/sfnt/ttcmap.c (tt_cmap8_char_next, tt_cmap12_next,
tt_cmap12_char_map_binary, tt_cmap13_next,

[sfnt] Improve handling of invalid SFNT table entries (#45987).
This patch fixes weaknesses in function `tt_face_load_font_dir'.
- It incorrectly assumed that valid tables are always at the
beginning. As a consequence, some valid tables after invalid
entries (which are ignored) were never seen.
- Duplicate table entries (this is, having the same tag) were not
rejected.
- The number of valid tables was sometimes too large, leading to
access of invalid tables.
* src/sfnt/ttload.c (check_table_dir): Add argument to return number
of valid tables.
Add another tracing message.
(tt_face_load_font_dir): Only allocate table array for valid
entries as returned by `check_table_dir'.
Reject duplicate tables and adjust number of valid tables
accordingly.

* src/gzip/ftgzip.c (ft_gzip_stream_close): Avoid memory leak.

a consequence, access to PCF files in general (which are normally
small files) should be much improved now as originally intended.

[autofit] Redesign code ranges (2/2).
This commit adds two fallback scripts (`latb', `latp') and
implements support for the no-base character ranges introduced in
the previous commit.

`script_uni_nobase_ranges' field.
(AF_DEFINE_SCRIPT_CLASS): Updated.
* src/autofit/afscript.h, src/autofit/afstyles.h: Add `latb' and
`latp' fallback scripts.
* src/autofit/afblue.dat: Add blue zones for Latin subscript and
superscript fallback scripts.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
* src/autofit/afglobal.h (AF_NOBASE): New style flag for no-base
characters.
(AF_STYLE_MASK): Updated.
* src/autofit/afglobal.c (SCRIPT): Updated.
(af_face_globals_compute_style_coverage): Handle new style flag.
* src/autofit/aflatin.c (af_latin_hints_apply): Handle new style
flag.
* src/autofit/afranges.h (SCRIPT): Use it to export no-base ranges.

[autofit] Redesign code ranges (1/2).
This patch introduces auxiliary code ranges that identify no-base
characters; they refer to glyphs of a script that should be hinted
without alignments to blue zones (mostly diacritics).
It also splits off ranges for fallback scripts that handle subscript
and superscript characters not covered by OpenType features. For
example, this greatly helps improve the hinting of various phonetic
alphabets, which contain a large amount characters that look like
superscript glyphs.
Finally, code ranges are updated to Unicode 8.0, and enclosed
characters are removed in general since they normally look better if
they stay unhinted.
* src/autofit/afranges.c (af_latn_uniranges): Updated to Unicode
8.0.
Split off superscript-like and subscript-like glyphs into...
(af_latb_uniranges, af_latp_uniranges): ... these two new arrays.
(af_xxxx_nobase_uniranges): New arrays that hold no-base characters
of the corresponding character ranges.
