4e7eeeec7b yet another logical transformation of the internals to make them
more consistent and understandable..

mainly, changing things like PS_Table  => PS_TableRec + *PS_Table

53b3fa1da5 * renaming stream functions to the FT_Subject_Action scheme:
FT_Seek_Stream         => FT_Stream_Seek
          FT_Skip_Stream         => FT_Stream_Skip
          FT_Read_Stream         => FT_Stream_Read
          FT_Read_Stream_At      => FT_Stream_Read_At
          FT_Access_Frame        => FT_Stream_Enter_Frame
          FT_Forget_Frame        => FT_Stream_Exit_Frame
          FT_Extract_Frame       => FT_Stream_Extract_Frame
          FT_Release_Frame       => FT_Stream_Release_Frame
          FT_Get_XXXX            => FT_Stream_Get_XXXX
          FT_Read_XXXX           => FT_Stream_Read_XXXX

          note also that:

          FT_New_Stream( filename, stream ) =>
            FT_Stream_Open( stream, filename )

          (the function doesn't create the FT_Stream structure, it simply
           initializes it for reading)

          FT_New_Memory_Stream( library, FT_Byte*  base, size, stream ) =>
            FT_Stream_Open_Memory( stream, const FT_Byte* base, size )

          FT_Done_Stream => FT_Stream_Close

          note that the name of the stream methods, defined in
          "include/freetype/ftsystem.h" have also been changed without
          problems:

            FT_Stream_IO    => FT_Stream_IOFunc
            FT_Stream_Close => FT_Stream_CloseFunc

4d57024d1c * moving all code related to glyph loaders to "internal/ftgloadr.h"
and "src/base/ftgloadr.c".

        Note also that the type "FT_GlyphLoader" is now a pointer to the
        structure "FT_GlyphLoaderRec"..

        within the "FT2_DEBUG" environment variable. See the comments within
        "ftdebug.c" for more details

        * include/freetype/internal/fttrace.h: new file to define the trace
        levels used for debugging. it is used both to define enums and
        toggle names for FT2_DEBUG

        * src/base/ftobjs.c, src/base/ftstream.c: FT_Assert renamed to
        FT_ASSERT

        * include/freetype/internal/ftextend.h, src/base/ftextend.c,
        src/base/Jamfile, src/base/rules.mk: removing "ftextend" from the

warning.

David Turner
662b344c23 * src/type1/t1objs.c (T1_Face_Init): fixed a bug that crashed the
library when dealing with certain weird fonts (like "Stalingrad",
        in "sadn.pfb". This font has no full font name entry.. )

        * src/base/ftoutln.c, include/freetype/ftoutln.h: added the
        FT_Outline_Check API to check the consistency of outline data

        * src/base/ftobjs.c (FT_Load_Glyph): added a call to the new
        FT_Outline_Check to ensure that loaded glyphs are valid. This
        allows certain fonts like "tt1095m_.ttf" to be loaded even though
        it appears they contain really funky glyphs..

        there still is a bug there though.. !!

(FT_Load_Glyph): "fixed" the bug that prevented embedded bitmaps from
        begin loaded when the auto-hinter is used.. This actually is a hack
        but will be enough until the internal re-design scheduled for
        FreeType 2.1

c8ad30a7a0 * src/base/ftglyph.c (FT_Glyph_To_Bitmap): re-ordered code for debugging
purposes..


    * src/smooth/ftsmooth.c (ft_smooth_render): fixed a nasty hidden bug where
    outline shifting wasn't correctly undone after bitmap rasterization. this
    created problems with certain glyphs (like '"' of certain fonts..) and
    the cache system..

14183ea0f8 First of all, a big thanks to Werner and Antoine for their latest work !!
* src/pshinter/pshalgo2.c (psh2_hint_table_init),
      src/pshinter/pshalgo1.c (psh1_hint_table_init): removed compiler
      warnings

    * include/freetype/cache/*, src/cache/*: yet another massive rewrite of
    the caching sub-system, in order to both increase performance and allow
    simpler cache sub-classing. As an example, the code for the image and
    sbit caches is now much simpler

    I still need to update the documentation in www/freetype2/docs/cache.html
    to reflect the new design though..

80b8d77024 Fixed a bug in `glnames.py' that prevented it from generating
correct glyph names tables.  This resulted in the unavailability of
certain glyphs like `Cacute', `cacute' and `lslash' in Unicode
charmaps, even if these were present in the font (causing problems
for Polish users).

* src/tools/glnames.py (mac_standard_names): Fixed.

* src/cache/ftlru.c (FT_Lru_Lookup_Node): Fixed a bug that prevented
correct LRU behaviour.

pool overflow occurs).
Function names are now all uniformly prefixed with `gray_'.

* src/smooth/ftgrays.c: Include <setjmp.h>.
(ErrRaster_MemoryOverflow): New macro.
(TArea): New type to store area values in each cell (using `int' was
too small on 16-bit systems).  <limits.h> is included to properly
get the needed data type.
(TCell, TRaster): Use it.
(TRaster): New element `jump_buffer'.
(gray_compute_cbox): Use `RAS_ARG' as the only parameter and get
`outline' from it.
