This large allocation is followed by careful initialization. Whatever
is missed should be initialized manually.

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 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.

Werner Lemberg e8ed2d621e Another round of cppcheck nitpicks.
The call was (from the top-level of the FreeType tree):

  cppcheck --force \
           --enable=all \
           -I /usr/include \
           -I /usr/local/include \

           -I include/freetype/internal \
           -DFT2_BUILD_LIBRARY \
           . &> cppcheck.log

using cppcheck git commit f7e93f99.

Note that cppcheck still can't handle `#include FOO' (with `FOO' a
macro).

David Turner c13e75fb1b * src/base/ftutil.c: ft_mem_alloc and related functions now return an
error if a negative size is passed in parameters.

    * src/cache/ftccache.c: make ftc_node_destroy FT_BASE_DEF, it needs to

    have an odd number of blue values (these are broken according to the
    specs).

    * src/cff/cffload.c, src/type1/t1load.c: modify the loaders to force
    even-ness of 'num_blue_values'. Also change the CFF loader so that
    invalid entries in index files are ignored.

David Turner e459d742e6 * include/freetype/internal/ftmemory.h, and a lot of other files !!:
changed the names of memory macros. Examples:

              MEM_Set   => FT_MEM_SET
              MEM_Copy  => FT_MEM_COPY
              MEM_Move  => FT_MEM_MOVE

              ALLOC     => FT_ALLOC
              FREE      => FT_FREE
              REALLOC   = >FT_REALLOC

            FT_NEW was introduced to allocate a new object from a _typed_
            pointer..

            note that ALLOC_ARRAY and REALLOC_ARRAY have been replaced
            by FT_NEW_ARRAY and FT_RENEW_ARRAY which take _typed_ pointer
            arguments.

            This results in _lots_ of sources being changed, but makes the
            code more generic and less error-prone..
