Alexei Podtelezhnikov fab53f7b1f * src/pcf/pcfutil.c (BSWAP16): Limit clang support.
These ancient builtins have been supported by clang since 2013. We
condition it somewhat stricter but still around 2017.  This is more
portable than `__has_builtin`. Fixes #1260.

Alexei Podtelezhnikov 4e61303a3b [raster] Small optimizations.
* src/raster/ftraster.c (New_Profile): Set important fields only and
delay setting `gProfile` until...
(End_Profile): ... it is checked to be valid here.
(Convert_Glyph): Updated.

Alexei Podtelezhnikov a35da2c093 * src/raster/ftraster.c (Convert_Glyph): Remove redundant check. 2023-10-18 18:44:00 +00:00
Alexei Podtelezhnikov 3fa5c84565 [raster] Fix linked profiles in contour loops.
This fixes a subtle bug when the last profile in a contour was not
properly short-circuited if it was still empty at `End_Profile`.
We finalize all linking in `Finalize_Profile_List` now and do nothing
else there.  The turns are added in `End_Profile`.

* src/raster/ftraster.c (Insert_Y_Turn): Moved up unchanged.
(End_Profile): Take care of turns but set only preliminary linking.
(Finalize_Profile_Table): Take care of linking and null-termination.
(Convert_Glyph): Adjusted accordingly.

Alexei Podtelezhnikov 153c038e3c [raster] Improve profile accounting.
* src/raster/ftraster.c (End_Profile): Do not initiate next profile.

2023-09-19 22:29:14 -04:00
Alexei Podtelezhnikov 95b0fe2a6d [base] Reintroduce `FT_SqrtFixed`.
The general square root calculations are not necessary in FreeType.
For vector normalization or length, FreeType uses special functions.
It is, however, required in the legacy CFF specifications.

* src/base/ftcalc.c (FT_SqrtFixed): New function that uses either
Babylonian or bit-wise algorithm, whichever is faster for the given
situation.
* include/freetype/internal/ftcalc.h (FT_SqrtFixed): Declare it.

`get_colr_glyph_paint` before calling `get_colr_glyph_paint` and not
`get_colr_layer`

2023-09-09 17:24:34 -04:00
Alexei Podtelezhnikov 7ad9d57c3b [type1, cid, type42] Streamline dictionary parsing.
When matching the keywords, we avoid calculating their lengths by
checking the stored values. This itself is a sufficient pre-check
before diving into `memcmp`. Therefore, we remove explicit check of
the first characters.

* include/freetype/internal/psaux.h (T1_FieldRec): Store length.
* src/cid/cidload.c (cid_parse_dict): Use `memcmp` and stored length.
* src/type1/t1load.c (parse_dict): Ditto.

Werner Lemberg ad20173942 [autofit] Fix typos.
This also reduces the used heap size by a large factor.

From Behdad.

* src/autofit/afcjk.h (AF_CJKAxisRec): Use `AF_BLUE_STRINGSET_MAX_LEN`.
* src/autofit/aflatin.h (AF_LatinAxisRec): Ditto.
