e1339133	2020-06-08T13:31:55	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.

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.

487913d9	2011-09-11T09:18:10	Slightly improve LZW_CLEAR handling. * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_CODE>: Ensure that subsequent (modulo garbage byte(s)) LZW_CLEAR codes are handled as clear codes. This also re-sets old_code and old_char to predictable values, which is a little better than using `random' ones if the code following LZW_CLEAR is invalid.
83cb6c00	2011-09-11T09:13:45	Add explicit LZW decompression stack size limit. Stack larger than 1<<LZW_MAX_BITS is never needed if prefix table is constructed correctly. It's even less than that, see e.g. libarchive code comment for a better size upper bound: http://code.google.com/p/libarchive/source/browse/trunk/libarchive/archive_read_support_filter_compress.c?r=3635#121 This patch adds explicit stack size limit, enforced when stack is realloced. An alternative is to ensure that code < state->prefix[code - 256] when traversing prefix table. Such check is less efficient and should not be required if prefix table is constructed correctly in the first place. * src/lzw/ftzopen.c (ft_lzwstate_stack_grow): Implement it.
86c3c69c	2011-09-11T09:08:40	Protect against loops in the prefix table. LZW decompressor did not sufficiently check codes read from the input LZW stream. A specially-crafted or corrupted input could create a loop in the prefix table, which leads to memory usage spikes, as there's no decompression stack size limit. * src/lzw/ftzopen.c (ft_lzwstate_io) <FT_LZW_PHASE_START>: First code in valid LZW stream must be 0..255. <FT_LZW_PHASE_CODE>: In the special KwKwK case, code == free_ent, code > free_ent is invalid.
