Werner Lemberg 9c98fbf634 Handle some border cases.
* include/freetype/config/ftstdlib.h (FT_USHORT_MAX): New macro.

* src/base/ftbitmap.c (FT_Bitmap_Convert): Protect against invalid
value of `target->rows'.

* src/psaux/t1decode.c (t1_decoder_parse_charstrings): Add check for
flex start.

* src/raster/ftrend1.c (ft_raster1_render): Check `width' and
`height'.

suzuki toshiya 65a449887d [base] Fix g++4.6 compiler warnings in src/base/*.c.
Passing uninitialized pointer to the buffer allocator is
not problematic theoretically (as far as the returned
pointer is checked before writing), but g++4.6 dislikes
it and warns by -Wuninitialized.  Initialize them by NULL.

* src/base/ftobjs.c (FT_Stream_New): Init `stream'.
(new_memory_stream): Ditto.
(FT_New_GlyphSlot): Init `slot'.
(FT_CMap_New): Init `cmap'.
(open_face_PS_from_sfnt_stream): Init `sfnt_ps'.
(Mac_Read_POST_Resource): Init `pfb_data'.
(Mac_Read_sfnt_Resource): Init `sfnt_data'.
* src/base/ftrfork.c (FT_Raccess_Get_DataOffsets):
Init `offsets_internal' and `ref'.
(raccess_guess_darwin_hfsplus): Init `newpath'.
(raccess_guess_darwin_newvfs): Ditto.
* src/base/ftbitmap.c (ft_bitmap_assure_buffer):
Init `buffer'.
* src/base/ftstroke.c (FT_Stroker_New): Init `stroker'.

David Turner e3654532ea * src/base/ftbitmap.c: fixing memory stomping bug in the
bitmap embolderner when the pitch of the source bitmap is
        *much* larger than its width

        * src/truetype/ttinterp.c: fixing aliasing-related compilation
        warning

David Turner 9ca782569c * include/freetype/internal/ftmemory.h, src/base/ftbitmap.c,
src/base/ftmac.c, src/base/ftrfork.c, src/lzw/ftzopen.c,
    src/raster/ftrend1.c, src/sfnt/ttpost.c, src/truetype/ttgxvar.c,
    src/type42/t42parse.c, src/winfonts/winfnt.c: hardening the code
    against out-of-bounds conditions when allocating arrays. This is
    for the cases where FT_NEW_ARRAY and FT_RENEW_ARRAY are not used
    already. Introducing the new FT_ALLOC_MULT and FT_REALLOC_MULT
    macros.

David Turner 6a681fa84a * src/autofit/afwarp.c: simple #ifdef to prevent compilation when
the warp hinter isn't active (it shouldn't, still experimental)

    * Jamfile, include/freetype/config/ftmodule.h: removed "gxvalid"
    and "otvalid" from the list of modules that are linked statically
    to a given FreeType library. Functionality has been moved to the
    "ftvalid" CVS module.

    note also that current Make-based build system still compiles the
    modules though...

    * include/freetype/config/ftoption.h: added FT_STRICT_ALIASING,
    which controls the definitions of the memory management functions
    to avoid warnings with recent versions of GCC. this macro is
    only here to be disabled, in case we detect problems with the
    new scheme.

    NOTE: disable macro to use the memory debugger. this will be fixed
          later !!

David Turner c562162834 * src/sfnt/ftbitmap.c, src/truetype/ttgload.c, src/sfnt/ttcmap.c:
removing compiler warnings (Visual C++ /W4)

        * Jamfile, src/otvalid/{otvcommn.h,otvgdef.c,otvgpos.c,otvgsub.c,
        otvjstf.c}: modified the code to use a different pre-processor trick
        to implement the OTV_NEST1, OTV_NEST2 and OTV_NEST3 macros. The code
        now compiles neatly with Visual C++. The 'otvalid' module has been
        put in the Jamfile build again.

Werner Lemberg 38e82be157 * include/freetype/ftbitmap.h (FT_Bitmap_Embolden): Minor
documentation improvements.

* include/freetype/ftoutln.h (FT_Outline_Embolden): Fix typos.

* src/base/ftbitmap.c (FT_Bitmap_Embolden): Add support for bitmap
of pixel_mode FT_PIXEL_MODE_GRAY2 or FT_PIXEL_MODE_GRAY4.
If xstr is larger than 8 and bitmap is of pixel_mode
FT_PIXEL_MODE_MONO, set xstr to 8 instead of returning error.

Werner Lemberg 71d7628175 * src/base/ftbitmap.c (FT_Bitmap_Embolden): Fix emboldening bitmap
of mode FT_PIXEL_MODE_GRAY.  Also add support for mode
FT_PIXEL_MODE_LCD and FT_PIXEL_MODE_LCD_V.
(ft_bitmap_assure_buffer): FT_PIXEL_MODE_LCD and FT_PIXEL_MODE_LCD_V
should have ppb (pixel per byte) 1.
Zero the padding when there's no need to allocate memory.

* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Handle slot->advance
too.
More suited emboldening strength.
