argument from `idx' to `strike_index'.
(FT_Size_Request_Type): Add FT_SIZE_REQUEST_TYPE_MAX to the end of
this enum.

FT_REQUEST_HEIGHT): New macros to get the width and height of a
request, in fractional pixels.
* include/freetype/internal/ftobjs.h (FT_Select_Metrics,
FT_Request_Metrics), src/base/ftobjs.c (FT_Select_Metrics,
FT_Request_Metrics): New base functions to set the font metrics. They
were part of FT_Select_Size/FT_Request_Size and are made independent
functions so that metrics are not set again and again.
* src/base/ftobjs.c (FT_Select_Size, FT_Request_Size): Metrics are set
only when driver's size_select/size_request is NULL. That is, drivers
should set the metrics themselves.
(FT_Match_Size): Round before matching. This was what we did and it
does cause some problems without rounding.
* src/cff/cffobjs.c (cff_size_select), src/truetype/ttdriver.c
(tt_size_select): Set the font metrics.
s/index/strike_index/.
The scaled metrics are always preferred over strikes' metrics, even
when some strike is selected. This is done because the strikes'
metrics are not reliable, e.g., the sign of the descender is wrong for
some fonts.
* src/cff/cffobjs.c (cff_size_request), src/truetype/ttdriver.c
(tt_size_request): Set the font metrics.
Call cff_size_select/tt_size_select when some strike is matched.

s/index/strike_index/.
* src/tools/test_afm.c, src/psaux/psconv.c: Older versions of these
files were committed. Just a catch-up.
(PS_Conv_ToFixed): Remove the `goto'.
(PS_Conv_ASCIIHexDecode, PS_Conv_EexecDecode): Speed up a little.
* src/sfnt/ttsbit.c (tt_face_load_sbit_strikes,
tt_face_load_strike_metrics), src/sfnt/ttsbit0.c
(tt_face_load_sbit_strikes, tt_face_load_strike_metrics): The
advertised metrics in `available_sizes' are different from those
actually used.

* src/psaux/psconv.c, src/psaux/psconv.h: New files to provide
conversion functions (e.g, PS real number => FT_Fixed) for the
PS_Parser and AFM_Parser. Some of the functions are taken, with some
modifications, from the psobjs.c
* src/psaux/psobjs.c: Use functions from psconv.c.
* include/freetype/internal/psaux.h, src/psaux/psauxmod.c:: Add

vertical metrics.
* src/cff/cffgload.c, src/cid/cidgload.c, src/pcf/pcfdrivr.c,

The fake metrics is monotone.
* src/truetype/ttgload.c (compute_glyph_metrics): Some fixes and
formattings in vertical metrics faking. There are still rooms for
improvements (and so do the CFF module).
(PCF_Glyph_Load), src/winfonts/winfnt.c (FNT_Load_Glyph): Don't set
the linear advance fields as they are only for the outline glyphs.
* include/freetype/freetype.h: Documentation updates/clarificatoins.
The meaning of FT_LOAD_FORCE_AUTOHINT is changed so that no real
change need be made to the code.
* src/base/ftobjs.c (FT_Load_Glyph): Resolve flag dependencies and
decide whether to use the auto-hinter according to documentation.
There should to be no real difference.
Some checks (e.g., is text height positve?) after the glyph is loaded.
(FT_Select_Size, FT_Request_Size): Scales are set to wrong values.
Be careful that scales won't be negative.

src/pcf/pcfdrivr.c (PCF_Size_Request, PCF_Size_Select),
src/winfonts/winfnt.c (FNT_Size_Request, FNT_Size_Select): Do size
matching for request of type NOMINAL and REAL_DIM.
* src/winfonts/winfnt.c (FNT_Face_Init): Print trace message when
`pixel_height' is used for nominal height.
* src/base/ftobjs.c (FT_Request_Size): Call `FT_Match_Size' if the
face is bitmap only and driver doesn't provide `request_size'. This
is added merely for completion as no driver satisfies the conditions.

`FT_Request_Size'.
* include/freetype/internal/ftobjs.h (FT_Match_Size),
src/base/ftobjs.c (FT_Match_Size): New function to match a size

a structure copy each time. Wooot. !
Make compiling instructions in docs/CUSTOMIZE work again.

260 KB of heap memory when loading tir24.pcf.Z

If xstr is larger than 8 and bitmap is of pixel_mode

FT_PIXEL_MODE_LCD and FT_PIXEL_MODE_LCD_V.
