* autogen.sh (copy_submodule_file), builds/toplevel.mk: Redirect
stderr to `/dev/null`.
* builds/toplevel.mk: Move code block to handle 'dlg' stuff into
`check_platform` conditional.
Also fix wildcard expressions for guarding `git submodule` commands.
Also make file copying work with non-Unix platforms (untested).
Other compilers are unchanged.
* builds/compiler/gcc-dev.mk, builds/compiler/gcc.mk (ANSIFLAGS):
s/-ansi/-std=c99/.
* builds/freetype.mk (FT_CFLAGS): Remove `-std=c99`.
* builds/unix/configure.raw: Handle C99.
Remove no longer needed test for gcc 4.6 and earlier.
* src/dlg/dlgwrap.c: Duplicate some feature test macros from
`dlg.c`, which must come first before loading standard headers. For
example, `freetype.h` loads `stdio.h` if compiled in debug mode.
* builds/unix/ax_pthread.m4: New file, taken from 'autoconf-archive'
git repository.
* builds/unix/configure.raw: Check for 'pthread'; also check whether
it works.
Based on a patch by Priyesh.
* include/freetype/internal/fttrace.h (FT_MAX_TRACE_LEVEL_LENGTH):
New macro.
* src/base/ftdebug.c, builds/windows/ftdebug.c (ft_log_handler):
Print logs after a fixed width to handle different lengths of
`FT_COMPONENT` entries.
Use `ft_strrchr` to check for final newline character.
We only support Visual C++ 2010 and newer.
* builds/windows/vc2010/script.bat: New windows batch file to copy
necessary 'dlg' files from `submodules/dlg` to `src/dlg`. This file
is used as a pre-built event in Visual C++.
* builds/windows/ftdebug.c: Synchronize with `src/base/ftdebug.c`.
* builds/windows/vc2010/freetype.vcxproj.filters: Add
`src/dlgwrap.c`.
* builds/windows/vc2010/freetype.vcxproj
(AdditionalIncludeDirectories): Add include files of dlg for 'Debug'
and 'Debug Static' configurations on both 'x64' and 'win32'
platforms.
(PreprocessorDefinitions): Add `FT_LOGGING` for 'Debug' and 'Debug
Static' configurations on both 'x64' and 'win32' platforms.
Add `DLG_STATIC' for 'Debug' configuration on 'x64' and 'win32'
platforms.
(DisableLanguageExtensions): We need to disable the `/Za` option
when building 'dlg' with FreeType as 'dlg' strictly follows the C99
standard. Visual C++ produces behaves unexpectedly when
compiling a C99 file with `/Za` option enabled.
* include/freetype/ftlogging.h (FT_Custom_Log_Handler): New function
typedef to store the custom callback logging function.

variable to support a custom callback logging function.
(FT_Logging_Callback): A new function typedef to print log using
custom callback logging function, which is set using
`FT_Set_Log_Handler`.
(FT_Log): Use it.
* src/base/ftdebug.c (FT_Set_Log_Handler,
FT_Set_Default_Log_Handler, FT_Logging_Callback): Add function
definitions.
* include/freetype/ftlogging.h: New header file.

`ftlogging.h`.
* src/base/ftdebug.c (ft_custom_trace_level): New variable.
(ft_debug_init): Update to support change of levels of tracing
components of FreeType at run-time.
(FT_Trace_Set_Level): New function to change the levels of tracing
components at run-time.
(FT_Trace_Set_Default_Level): New function to reset the levels of
tracing components back to default.
* include/freetype/internal/ftdebug.h (FT_LOGGING_TAG,
FT_LOGGING_TAG_): New macros to resolve the value of `FT_COMPONENT'
into a string.
(ft_add_tag, ft_remove_tag): New functions to add and remove dlg tags.
* src/base/ftdebug.c: Add new variables to control the logging of
timestamp and name of `FT_COMPONENT` along with actual logs.
(ft_add_tag, ft_remove_tag): Add function definitions.
(ft_log_handler): Updates to print timestamp and name of
`FT_COMPONENT`.
(ft_debug_init) [FT_LOGGING]: Users can now control the logging of
timestamp and name of `FT_COMPONENT` by adding tags in the
`FT2_DEBUG` environment variable.
* include/freetype/internal/ftdebug.h: Added dlg's header files.
(FT_LOG): New macro to redirect trace logs to dlg's API's whenever
`FT_LOGGING' is defined.
(ft_logging_init, ft_logging_deinit): New functions to handle
initialization and uninitialization of logging related variables.
(ft_log_handler): New function to handle logs of FreeType.
* src/base/ftdebug.c: Add necessary logging related variables.
(ft_logging_init, ft_logging_deinit, ft_log_handler): Add function
definitions.
* src/base/ftinit.c (FT_Init_FreeType) [FT_LOGGING]: Call
`ft_logging_init`.
(FT_Done_FreeType) [FT_LOGGING]: Call `ft_logging_deinit`.
* src/base/ftobjs.c (FT_New_Library): Call `ft_debug_init` only if
`FT_LOGGING` is not defined.
* autogen.sh (copy_submodule_files): New script to copy all the
necessary source and include files from `submodules/dlg` to
`src/dlg`.
* src/dlg/dlgwrap.c: New wrapper file for `src/dlg.c`. It enables
the build of 'dlg' if the `FT_LOGGING` macro is defined.
* src/dlg/rules.mk: New sub-Makefile.
* builds/freetype.mk (DLG_DIR): New variable to include the
header files of the 'dlg' library.
(INCLUDES): Add `DLG_DIR`.
(FT_CFLAGS): Add `-std=c99' flag.
Include `src/dlg/rules.mk` file to build 'dlg' library.
(OBJ_S, OBJ_M): Add `DLG_OBJS_M` and `DLG_OBJS_S`.
* builds/toplevel.mk: For builds directly from the git repository
we need to copy files from `submodule/dlg` to `src/dlg`.
* include/freetype/config/ftoption.h, devel/ftoption.h (FT_LOGGING):
New macro to enable or disable the logging facility in FreeType.

This corresponds to the following commits in the ttfautohint git
repository:
bb6842bd3bd437b7b4a7921b0376c860f5e73d18 Typo, formatting.
d5c91ddb1cb310257a3dfe9a8e20e1fc51335faa Add Medefaidrin script.
* src/autofit/afblue.dat: Add blue zone data for Medefaidrin.
* src/autofit/afblue.c, src/autofit/afblue.h: Regenerated.
* src/autofit/afscript.h: Add Medefaidrin standard characters.
* src/autofit/afranges.c, src/autofit/afstyles.h: Add Medefaidrin
data.
* scr/tools/scripts/make_distribution_archives.py: (_TOP_DIR,
_SCRIPT_DIR): Updated to new location.
(main): s/shutils.copyfile/shutils.copy/ to preserve file
permissions.
(main): Prefix source file paths with `git_dir` while copying files
to allow calls of the script from other places than the top-level
directory.
Towards the end of the the function there is a call to
`FT_Outline_Get_CBox` that retrieves the glyph bbox in scaled units.
That sets `horiBearing{X,Y}` and `vertBearingX` but `vertBearingY`
is left alone, and is not scaled.
Patch from Eric Muller <emuller@amazon.com>.
