include/freetype/freetype.h (FT_Bitmap_Size): `height' is now
defined to return the baseline-to-baseline distance. This was
already the value returned by the BDF and PCF drivers.
The `width' field now gives the average width. I wasn't able to
find something better. It should be taken as informative only.
New fields `size', `x_ppem', and `y_ppem'.
* src/pcf/pcfread.c (pcf_load_font): Updated to properly fill
FT_Bitmap_Size.
Do proper rounding and conversion from 72.27 to 72 points.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Updated to properly fill
FT_Bitmap_Size.
Do proper rounding and conversion from 72.27 to 72 points.
* src/sfnt/sfobjs.c (sfnt_load_face): Updated to properly fill
FT_Bitmap_Size.
* src/winfonts/winfnt.c (FNT_Face_Init): Updated to properly fill
FT_Bitmap_Size.
Redesigning the FNT driver to return multiple faces, not multiple
strikes. At least one font (app850.fon from WinME) contains
different FNT charmaps for its subfonts. Consequently, the previous
design of having multiple bitmap strikes in a single font face fails
since we have only one charmap per face.
* include/freetype/internal/fnttypes.h (FNT_Size_Rec): Removed.
(FNT_FaceRec): Remove `num_fonts' field and replace `fonts' with
`font'.
* src/base/ftwinfnt.c (FT_Get_WinFNT_Header): Updated.
* src/winfonts/winfnt.c (fnt_font_load): Don't set pixel_width equal
to pixel_height.
(fnt_face_done_fonts): Removed.

(fnt_face_get_dll_font): This. Add second function argument to
select face index.
Updated to load just one subfont.
(fnt_font_done, FNT_Face_Done): Updated.
(FNT_Face_Init): Handle `face_index'.
Updated.
(FNT_Size_Set_Pixels): Simplified; similar to BDF and PCF, the
bitmap width is now ignored.
(FNT_Load_Glyph): Updated.
Fix glyph index computation.
(winfnt_driver_class): Updated.
computation of glyph_index.
(FNT_Size_Set_Pixels): To find a strike, first check pixel_height
only, then try to find a better hit by comparing pixel_width also.
Without this fix it isn't possible to access all strikes.
Also compute metrics.max_advance to be in sync with other bitmap
drivers.
* src/base/ftobjs.c (FT_Set_Char_Size): Remove redundant code.
(FT_Set_Pixel_Size): Assign value to `metrics' after validation of
arguments.
Synchronize computation of height and width for bitmap strikes. The
`width' field in the FT_Bitmap_Size structure is now only useful to
enumerate different strikes. The `max_advance' field of the
FT_Size_Metrics structure should be used to get the (maximum) width
of a strike.
* src/bdf/bdfdrivr.c (BDF_Face_Init): Don't use AVERAGE_WIDTH for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.
* src/pcf/pcfread.c (pcf_load_font): Don't use RESOLUTION_X for
computing `available_sizes->width' but make it always equal to
`available_sizes->height'.
* src/truetype/ttdriver.c (Set_Pixel_Sizes): Pass only single
argument to function.
* src/psnames/psmodule.c (ps_unicode_value): Handle `.' after
`uniXXXX' and `uXXXX[X[X]]'.

ft_glyphslot_free_bitmap
ft_glyphslot_alloc_bitmap
ft_glyphslot_set_bitmap
these are much more convenient to use than managing the FT_GLYPH_OWN_BITMAP
flag manually. the font drivers have been modified to use them as well.

added a Windows .FNT specific API (mostly for Wine). Also fixed a nasty
bug in the header loader which would cause invalid memory overwrites
* include/freetype/config/ftoption.h, src/autohint/ahglobal.h,
src/autohint/ahglobal.c, src/autohint/ahglyph.c,
src/autohint/ahtypes.h:
included David Chester's patches to the auto-hinter in order to
slightly improve the output. Note that everything is controlled
through the new FT_CONFIG_OPTION_CHESTER_HINTS defined at the
end of "ftoption.h", there are also individual FT_CONFIG_CHESTER_XXX
macros to control individual "features".
Note that all improvements are enabled by default, but can be
tweaked for optimization and testing purpose. The configuration
macros will most likely disappear in the short future.
