Werner Lemberg 1d6773e6d9 Add check for librt, needed for `ftbench' (#52824).
* builds/unix/configure.raw: Call AC_USE_SYSTEM_EXTENSIONS.
(LIB_CLOCK_GETTIME): Define; this will hold `-lrt' if necessary.

* builds/unix/unix-cc.in (LIB_CLOCK_GETTIME): New variable.

Ewald Hew 21bd9c2f8c [psaux] Fix Type 1 glyphs with too many stem hints.
According to the CFF specification, charstrings can have up to 96 stem
hints. Due to hint replacement routines in Type 1 charstrings, some
glyphs are rejected by the Adobe engine, which implements the above
limit. This fix turns off hinting for such glyphs.

* src/psaux/pshints.c (cf2_hintmap_build): Reset the error from calling
`cf2_hintmask_setAll' on a problematic Type 1 charstring and turn off
hinting.

Werner Lemberg 3758aed760 Add `FT_Done_MM_Var'.
This is necessary in case the application's memory routines differ
from FreeType.  A typical example is a Python application on Windows
that calls FreeType compiled as a DLL via the `ctypes' interface.

* include/freetype/ftmm.h, src/base/ftmm.c (FT_Done_MM_Var): Declare
and define.

* docs/CHANGES: Updated.

it.

Werner Lemberg 55d6abea5d * src/truetype/ttgxvar.c (ft_var_to_design): Remove dead code.

reverted.

Werner Lemberg 2df73b397d [sfnt] Fix charmap type 2 iterator (#52646).
The subsetted demo font of the report that exhibits the bug has a
very unusual type 2 cmap for Unicode(!): It contains only two
sub-headers, one for one-byte characters (covering the range 0x20 to
0xFA), and a second one for higher byte 0x01 (just for character
code U+0131).

Before this commit, the iterator wasn't able to correctly handle a
sub-header for higher byte 0x01.

windows is too fragile.

Werner Lemberg ea68f1c8d3 [docmaker] Fix code section parsing.
Stuff like

Werner Lemberg 98ba0c4a37 New `ftdriver.h' file, covering all driver modules.
This reduces redundancy and increases synergy; it also reduces the

Werner Lemberg 40db4a9954 Allow (again) encoding vectors with more than 256 elements (#52464).
In version 2.6.1, this has been disallowed to better reject
malformed fonts; however, this restriction was too strong.  This
time, we only take the first 256 elements into account, since
encoding arrays are always accessed with a 8bit integer, according
to the PostScript Language Reference.

* src/type1/t1load.c (parse_encoding): Implement it.

Werner Lemberg 8f4851997b [unix] Install a massaged `ftoption.h' file (#51780).
* builds/unix/configure.raw (ftoption_set, ftoption_unset): New
auxiliary functions to construct...
(FTOPTION_H_SED): ... this new variable.
Apply it as a sed argument while copying `ftoption.h' to the
`builds/unix' directory (using `AC_CONFIG_FILES').
Simplify code of test that checks cpp's computation of bit length
(the test previously created an empty `ftoption.h' file and deleted
it immediately afterwards); without this change, it can happen on my
GNU/Linux box that `configure's execution of `config.status' doesn't
create `ftoption.h' (no idea why this happens).

* builds/unix/install.mk (install): Install
`builds/unix/ftoption.h'.

* builds/unix/unix-def.in (DISTCLEAN): Updated.

* builds/unix/.gitignore: Updated.
