These tests should mainly help avoid unnecessarily large memory
allocations in case of malformed fonts.
* src/truetype/ttgxvar.c (ft_var_readpackedpoints,
ft_var_readpackeddeltas): Check number of points against stream
size.
(ft_var_load_avar): Check `pairCount' against table length.
(ft_var_load_gvar): Check `globalCoordCount' and `glyphCount'
against table length.
(tt_face_vary_cvt): Check `tupleCount' and `offsetToData'.
Fix trace.
(TT_Vary_Apply_Glyph_Deltas): Fix trace.
Free `sharedpoints' to avoid memory leak.
This implementation renders the entire line segment at once without
subdividing it into scanlines. The main speed improvement comes from
reducing the number of divisions to just two per line segment, which
is a bare minimum to calculate cell coverage in a smooth rasterizer.
Notably, the progression from cell to cell does not itself require any
divisions at all. The speed improvement is more noticeable at larger
sizes.
* src/smooth/ftgrays.c (gray_render_line): New implementation.
=========================
Tag sources with `VER-2-6-1'.
* docs/VERSION.DLL: Update documentation and bump version number to
2.6.1.

* include/freetype/freetype.h (FREETYPE_PATCH): Set to 1.
* builds/unix/configure.raw (version_info): Set to 18:1:12.
* CMakeLists.txt (VERSION_PATCH): Set to 1.
* src/autofit/afmodule.c [AF_DEBUG_AUTOFIT]: Ensure C linking for
dumping functions.
* src/bzip2/ftbzip2.c (ft_bzip2_file_fill_input), src/gzip/ftgzip.c
(ft_gzip_file_fill_input): In case of an error, adjust the limit to
avoid copying uninitialized memory.
* src/bzip2/ftbzip2.c (ft_bzip2_file_fill_output), src/gzip/ftgzip.c
(ft_gzip_file_fill_output): In case of an error, adjust the limit to
avoid copying uninitialized memory.
* src/sfnt/ttcmap.c (tt_cmap4_char_map_linear): Add code to better
skip invalid segments.
If searching the next character, provide a more efficient logic to
speed up the code.
Thanks to Danh Hong <danhhong@gmail.com> for guidance with blue zone
characters!
* src/autofit/afblue.dat: Add blue zone data for Lao.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
* src/autofit/afscript.h: Add Lao standard characters.
* src/autofit/afranges.c: Add Lao data.
* src/autofit/afstyles.h: Add Lao data.
open_face_from_buffer() frees passed buffer if valid font
is not found. But if copying to the buffer is failed,
the allocated buffer should be freed within the caller.
* src/base/ftobjs.c (open_face_PS_from_sfnt_stream): Free
the buffer `sfnt_ps' if an error caused before calling
open_face_from_buffer().
(Mac_Read_sfnt_Resource): Free the buffer `sfnt_data' if
an error caused before calling open_face_from_buffer();
Suggested by Hin-Tak Leung.
* src/bzip2/ftbzip2.c (ft_bzip2_stream_io), src/gzip/ftgzip.c
(ft_gzip_stream_io), src/lzw/ftlzw.c (ft_lzw_stream_io): Do it.
