2002-02-28  David Turner   <david@freetype.org>

        * src/sfnt/ttload.c (TT_Load_Names): simplifying and securing the
        names table loader. Invalid individual name entries are now handled
        correctly. This allows the loading of very buggy fonts like
        "foxjump.ttf" without allocating tons of memory and causing crashes..

        * src/otlayout/otlcommon.h, src/otlayout/otlcommon.c: adding (still
        experimental) code for OpenType Layout tables validation and parsing

        * src/type1/t1cmap.h, src/type1/t1cmap.c: adding (still experimental)
        code for Type 1 charmap processing

        * src/sfnt/ttcmap0.c: completing the experimental SFNT charmap
        processing

        * include/freetype/internal/ftobjs.h: adding validation support as
        well as internal charmap object definitions (FT_CMap != FT_CharMap)

2002-02-24  David Turner   <david@freetype.org>

        * 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



        * moving all memory and list management code to "src/base/ftutil.c"
        (previously in "ftobjs.c" and "ftlist.c" respectively)

        * 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"..


        * renaming "ft_glyph_own_bitmap" into "FT_GLYPH_OWN_BITMAP"

	* Version 2.0.8 released.
	=========================


2002-02-08  David Turner  <david@freetype.org>

	* docs/CHANGES: Updating for 2.0.8.

	removing `FT_Get_Next_Char' from the API (temporarily).

	release.

2002-02-07  David Turner  <david@freetype.org>

	the AVERAGE_WIDTH property.

2002-02-06  David Turner  <david@freetype.org>

	* src/sfnt/sfobjs.c (SFNT_Load_Face): Since many fonts embedded in
	PDF documents do not include 'cmap', 'post' and 'name' tables, the
	SFNT face loader has been changed to not immediately report an
	error if these are not present.

	Note that the specification _requires_ these tables, but Adobe
	seems to ignore it completely.

	* src/sfnt/ttcmap.c: Removing compiler warnings.

	* src/pcf/pcfread.c (pcf_read_TOC): Use FT_UInt.

	Use FT_Int.
	(pcf_get_bitmaps, pcf_get_encodings): Handle invalid PCF fonts
	better (delaying format checks out of FT_Access_Frame ..
	FT_Forget_Frame blocks to avoid leaving the stream in an incorrect
	state when encountering an invalid PCF font).

	* src/pcf/pcfdriver.c (PCF_Done_Face): Renamed to ...
	(PCF_Face_Done): This.
	(PCF_Init_Face): Renamed to ...
