* docs/CHANGES: Updated.
2004-06-10 David Turner <david@freetype.org>
* src/base/ftobject.c, src/base/fthash.c, src/base/ftexcept.c,
src/base/ftsysio.c, src/base/ftsysmem.c, src/base/ftlist.c:
removing obsolete files
* src/base/ftobject.c, src/base/fthash.c, src/base/ftexcept.c,
src/base/ftsysio.c, src/base/ftsysmem.c, src/base/ftlist.c: Removed.
Obsolete.
* src/raster/ftraster.c (Alignment, PAlignment): New union to fix
problems with 64bit systems.
(AlignProfileSize): Use it.
2004-06-08 David Turner <david@freetype.org>
* include/freetype/freetype.h (FT_Glyph_Metrics, FT_GlyphSlotRec),
src/autofit/afloader.c, src/autohint/ahhint.c:
moved the definition of 'lsb_delta' and 'rsb_delta' from FT_GlyphMetrics
to FT_GlyphSlotRec. The old location did BREAK BINARY COMPATIBILITY
of the library !!
* include/freetype/freetype.h (FT_GlyphMetrics): Move `lsb_delta'
and `rsb_delta' elements to...
(FT_GlyphSlotRec): Here to retain binary compatibility with older
FreeType versions.
Update all users.
* src/sfnt/sfobjs.c: removing compiler warning
* src/sfnt/sfobjs.c (tt_face_get_name): Remove compiler warning.
* src/winfonts/winfnt.c: adding missing initialization of the
slot->metrics.width and slot->metrics.height when loading a Windows
FNT glyph. Thanks to Huw Davies
* src/winfonts/winfnt.c (FNT_Load_Glyph): Add missing initialization
of slot->metrics.width and slot->metrics.height when loading a
Windows FNT glyph. Thanks to Huw Davies.
* include/freetype/cache/ftcmru.h, src/cache/ftcbasic.c,
src/cache/ftccache.c, src/cache/ftcglyph.c, src/cache/ftcmanag.c,
src/cache/ftcsbits.c:
fixing some annoying bugs and inefficiencies in the cache sub-system.
* include/freetype/cache/ftcmru.h (FTC_MruNode_CompareFunc): Change
return type to FT_Bool.
* src/cache/ftbasic.c (ftc_basic_family_compare): Change return
type to FT_Bool.
* src/cache/ftccache.c (FTC_Cache_Init, ftc_cache_init): Make
the former call the latter, not vice versa.
(FTC_Cache_Done, ftc_cache_done): Ditto.
* src/cache/ftcglyph.c (FTC_GNode_Compare, ftc_gnode_compare): Make
the former call the latter, not vice versa.
(FTC_GCache_Init, ftc_gcache_init): Ditto.
(FTC_GCache_Done, ftc_gcache_done): Ditto.
* src/cache/ftcimage.c (FTC_INode_Free, ftc_inode_free): Make the
former call the latter, not vice versa.
(FTC_INode_Weight, ftc_inode_weight): Ditto.
* src/cache/ftcmanag.c (ftc_size_node_compare,
ftc_size_node_compare_faceid, ftc_face_node_compare): Change return
type to FT_Bool.
* src/cache/ftcsbits.c (FTC_SNode_Free, ftc_snode_free): Make the
former call the latter, not vice versa.
(FTC_SNode_Weight, ftc_snode_weight): Ditto.
(FTC_SNode_Compare, ftc_snode_compare): Ditto.
* src/cache/ftcsbits.c: Fix some bugs and inefficiencies in the cache
sub-system.

Improve inter-letter spacing for autohinted glyphs.
* include/freetype/freetype.h (FT_Glyph_Metrics): Add elements
`lsb_delta' and `rsb_delta'.
* src/autohint/ahhint.c (ah_hinter_load): Set `lsb_delta' and
`rsb_delta' in slot->metrics and tune side bearings slightly.

and `gvar' tables; the Multiple Masters API has been slightly
extended to cope with the new functionality).
- The `FT_Glyph_Metrics' structure has been extended: The elements
- The `FT_GlyphSlotRec' structure has been extended: The elements
`lsb_delta' and `rsb_delta' give the difference between hinted
and unhinted left and right side bearings if autohinting is
active. Using those values can improve the inter-letter spacing
considerably. See the documentation of `FT_Glyph_Metrics' and
considerably. See the documentation of `FT_GlyphSlotRec' and
the `ftstring' demo program how to use it.
