7b37145b63 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..

d4b4ccb8b3 * include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c:
improvements to the memory debugger to report more information in
	case of errors. Also, some allocations that occured through
	REALLOC couldn't be previously catched correctly..

864a36ad78 replaced liberal uses of "memset" by the "MEM_Set" macro call
(some platforms don't provide this ANSI function !!)

some changes to "ftsystem.c" implementations in order to use
the new memory debugger on Unix, VMS and Amiga too !!

c1b7ca25b8 * include/freetype/internal/ftmemory.h, src/base/ftdbgmem.c: modified
the debugging memory manager to report the location (source file name
        + line number) where leaked memory blocks are allocated in the source
        file..  funny, isn't it ??

6a36a6db05 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.
(t1_standard_strings): Some fixes and renamed to ...
(sid_standard_names): This.
(t1_expert_encoding): Fixed.
(the_adobe_glyph_list): Renamed to ...
(adobe_glyph_names): This.
(the_adobe_glyphs): Renamed to ...
(adobe_glyph_values): This.
(dump_mac_indices, dump_glyph_list, dump_unicode_values, main):
Updated.
* src/psnames/pstables.h: Regenerated.
* src/psnames/psmodule.c (PS_Unicode_Value): Fix offset.
Fix return value.
Use `sid_standard_table' and `ps_names_to_unicode' instead of
`t1_standard_glyphs' and `names_to_unicode'.
(PS_Macintosh_Name): Use `ps_glyph_names' instead of
`standard_glyph_names'.
(PS_Standard_Strings): Use `sid_standard_names' instead of
`t1_standard_glyphs'.
* doc/BUGS, doc/TODO: New documents.
* src/cache/ftlru.c (FT_Lru_Lookup_Node): Fixed a bug that prevented
correct LRU behaviour.
setjmp() and longjmp() are now used for rollback (i.e. when memory
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.
(gray_record_cell): Use longjmp().
(gray_set_cell): Use gray_record_cell() for error handling.
(gray_render_line, gray_render_conic, gray_render_cubic): Simplify.
(gray_convert_glyph_inner): New function, using setjmp().
(gray_convert_glyph): Use it.


Provide a public API to manage multiple size objects for a given
FT_Face in the new header file `ftsizes.h'.

* include/freetype/ftsizes.h: New header file,
* include/freetype/internal/ftobjs.h: Use it.
Remove declarations of FT_New_Size and FT_Done_Size (moved to
ftsizes.h).
* include/freetype/config/ftheader.h (FT_SIZES_H): New macro.
* src/base/ftobjs.c (FT_Activate_Size): New function.

78b6740ff2 * include/freetype/ftsizes.h, src/base/ftobjs.c, src/cache/ftcmanag.c:
added a new header, named "ftsizes.h" (FT_SIZES_H) to provide a public
	API to manage multiple size objects for a given FT_Face.

686901a1a5 modified the TrueType interpreter to let it
use the new trigonometric functions provided in "fttrigon.h". This
        gets rid of some old 64-bit computation routines, as well as many
        warnings when compiling the library with the "long long" 64-bit
        integer type.

8e86015f39 * src/base/ftcalc.c (FT_DivFix): fixed a bug in the 64-bit code that
created incorrect scale factors !!

    * src/autohint/ahglobal.c, src/autohint/ahglyph.c, src/autohint/ahhint.c:
    fixed the incorrect blue zone computations, and improved the composite
    support. Note that these changes result in improved rendering, while
    sometimes introducing their own artefacts. That's probably the last
    big change to the autohinter before the introduction of its complete
    replacement..
