Werner Lemberg fbe2fe4c75 Handle some integer overflow run-time errors (#46149, #48979).
This commit (mainly for 32bit CPUs) is the first of a series of
similar commits to handle known integer overflows.  Basically, all
of them are harmless, since they affect rendering of glyphs only,
not posing security threats.  It is expected that fuzzying will show
up more overflows, to be fixed in due course.

The idea is to mark places where overflows can occur, using macros
that simply cast to unsigned integers, because overflow arithmetic
is well defined in this case.  Doing so suppresses run-time errors
of sanitizers without adding computational overhead.

* include/freetype/internal/ftcalc.h (OVERFLOW_ADD_INT,
OVERFLOW_SUB_INT, OVERFLOW_MUL_INT, OVERFLOW_ADD_LONG,
OVERFLOW_SUB_LONG, OVERFLOW_MUL_LONG): New macros.

* src/base/ftcalc.c (FT_RoundFix, FT_CeilFix, FT_Matrix_Multiply,
FT_Matrix_Multiply_Scaled, FT_Vector_Transform_Scaled,
ft_corner_orientation): Use new macros.

* src/base/ftoutln.c (FT_Outline_Get_Orientation): Use new macros.

Werner Lemberg 392cf22f8a Another adjustment to header locations.
This change is a result of a discussion thread on freetype-devel

  http://lists.nongnu.org/archive/html/freetype-devel/2015-06/msg00041.html

Re-introduce the `freetype2' subdirectory for all FreeType header
files after installation, and rename the `freetype2' subdirectory in
the git repository to `freetype'.

* include/freetype2: Renamed to...
* include/freetype: This.

* CMakeLists.txt (PUBLIC_HEADERS, PUBLIC_CONFIG_HEADERS,
PRIVATE_HEADERS): Updated.
Update creation of `ftconfig.h'.
Install generated `ftconfig.h'.

* Jamfile (HDRMACRO, RefDoc), autogen.sh: Updated.

* builds/amiga/include/config/ftconfig.h, builds/freetype.mk
(PUBLIC_DIR), builds/symbian/bld.inf, builds/toplevel.mk (work),
builds/unix/freetype2.in: Updated.

* builds/unix/freetype-config.in: Updated.
* builds/unix/configure.raw: Don't check for `rmdir'.
* builds/unix/unix-def.in (DELDIR): Use `rm -rf', which is portable
according to the autoconf info manual.
* builds/unix/install.mk (install, uninstall,
distclean_project_unix): Update and simplify.

* builds/wince/*, builds/windows/*: Updated.

* devel/ft2build.h, include/ft2build.h: Updated.

* include/freetype2/config/ftheader.h,
include/freetype2/internal/ftserv.h,
include/freetype2/internal/internal.h: Update all header file
macros.

* docs/*: Updated.

Werner Lemberg fae3820764 Simplify header file hierarchy.
This large patch changes the header file directory layout from
`include/freetype/...' to `include/...', effectively removing one
level.  Since the file `ft2build.h' is also located in `include'
(and it stays there even after installation), all FreeType header
files are now in a single directory.

Applications that use (a) `freetype-config' or FreeType's
`pkg-config' file to get the include directory for the compiler, and
(b) the documented way for header inclusion like

  #include <ft2build.h>
  #include FT_FREETYPE_H
  ...

don't need any change to the source code.

* include/freetype/*: Move up to...
* include/*: ... this directory.

* builds/amiga/include/freetype/*: Move up to...
* builds/amiga/include/*: ... this directory.

*/*: Essentially do `s@/freetype/@/@' where appropriate.

* CMakeList.txt: Simplify.
* builds/unix/freetype-config.in, builds/unix/freetype2.in: For
`--cflags', return a single directory.
* builds/unix/install.mk (install): No longer try to remove `cache'
and `internal' subdirectories; instead, remove the `freetype'
subdirectory.

2002-09-27 11:09:23 +00:00
David Turner b08fe2dc7a * massive re-formatting changes to many, many source files. I don't
want to list them all here. The operations performed were all logical
    transformations of the sources:

      - trying to convert all enums and constants to CAPITALIZED_STYLE, with
        #define definitions like

          #define  my_old_constants   MY_NEW_CONSTANT

      - big, big update of the documentation comments

    * include/freetype/freetype.h, src/base/ftobjs.c, src/smooth/ftsmooth.c,
    include/freetype/ftimage.h: adding support for LCD-optimized rendering
    though the new constants/enums:

      FT_RENDER_MODE_LCD, FT_RENDER_MODE_LCD_V
      FT_PIXEL_MODE_LCD,  FT_PIXEL_MODE_LCD_V

    this is still work in progress, don't expect everything to work correctly
    though most of the features have been implemented.

    * adding new FT_LOAD_XXX flags, used to specify both hinting and rendering
    targets:

      FT_LOAD_TARGET_NORMAL :: anti-aliased hinting & rendering
      FT_LOAD_TARGET_MONO   :: monochrome bitmaps
      FT_LOAD_TARGET_LCD    :: horizontal RGB/BGR decimated hinting & rendering
      FT_LOAD_TARGET_LCD_V  :: vertical RGB/BGR decimated hinting & rendering

    note that FT_LOAD_TARGET_NORMAL is 0, which means that the default
    behaviour of the font engine is _unchanged_.
