Werner Lemberg d924a66a5c * src/*: Don't use more than one '\n' in `FT_TRACE` and `FT_ERROR`.
This ensures good logging output, with all lines having a proper
prefix (if requested).

This is a continuation of a similar patch from 2020-12-02, which
missed some locations.

David Turner e13391333f Make macros for header file names optional.
We no longer have to take care of the 8.3 file name limit; this
allows us (a) to introduce longer, meaningful file names, and (b) to
avoid macro names in `#include' lines altogether since some
compilers (most notably Visual C++) doesn't support this properly.

*/*: Replace

   #include FOO_H

with

   #include <freetype/foo.h>

or something similar.  Also update the documentation.

Werner Lemberg a9af691481 Fix handing of `FT_Bool'.
Before this commit we had code like

  (FT_Bool)( globals->glyph_styles[gindex] & 0x8000)

Since `FT_Bool' is defined to be an `unsigned char', the code
evaluated to something like

  (unsigned char)( 0x8532 & 0x8000)

which in turn expanded to

  (unsigned char)( 0x8000)

and finally yielded 0x00 – i.e., false – not as expected.

Problem reported and analyzed by Tony Smith <tony.smith@macro4.com>.

* include/freetype/fttypes.h (FT_BOOL): Add a comparison against
zero so that we always have a Boolean expression.

*/*: Replace castings to `FT_Bool' with calls to `FT_BOOL' where
possible.

Werner Lemberg 9ac9060df0 [GSoC] src/*.*: Convert block comments to `light' style.
This monster commit was created by applying Nikhil's scripts
`docconverter.py' and `markify.py' to all C header and source files,
followed up by minor manual clean-up.

No change in functionality, of course.

I used commit f7419907bc6044b9b7057f9789866426c804ba82 from
https://github.com/nikramakrishnan/freetype-docs.git.

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.

Ewald Hew 766f529a31 Rename files.
Replace the `cf2' file name prefix with `ps' as the Adobe engine
will be used for both PostScript Types 1 and 2 (CFF) instead of just
CFF.

s/cf2/ps/ for all following.

* src/psaux/cf2*: Rename files.
* src/psaux/*: Update includes.

* src/psaux/Jamfile (_sources), src/psaux/rules.mk (PSAUX_DRC_SRC,
PSAUX_DRV_H): Update file references.
