`loadSize' and `loadStack'.

compiler errors/warnings when TT_CONFIG_OPTION_EMBEDDED_BITMAPS is not
defined.
* src/sfnt/ttmtx.c (tt_face_load_hmtx, tt_face_get_metrics): Fix
possible segment faults for the non-FT_OPTIMIZE_MEMORY'ed versions.
(finally!)
For most OpenType tables, `tt_face_load_xxxx' simply loads the table
and `face->root' is set later in `sfnt_load_face'. Here, we try to
make this work for _all_ tables.
* src/sfnt/ttsbit.c, src/sfnt/ttsbit0.c, src/sfnt/ttload.c,
src/sfnt/ttmtx.c: all `tt_face_load_xxxx' should load the table and
then exit. Error handling or setting face->root is done later in
`sfnt_load_face'.
Pretty trace messages.
* src/sfnt/sfobjs.c (sfnt_load_face): Work harder.
Mac bitmap-only fonts are not scalable.
Check that `face->header.Units_Per_EM' is not zero.
(LOAD_, LOADM_): Pretty trace messages.
* src/sfnt/ttsbit0.c (tt_face_load_strike_metrics): Read metrics from
`eblc'.
* src/sfnt/ttcmap.c (tt_face_build_cmaps), src/sfnt/ttpost.c
(load_format_20, load_format_25, tt_face_get_ps_name): Use
face->max_profile.numGlyphs, instead of face->root.num_glyphs.

src/sfnt/Jamfile, src/sfnt/rules.mk, src/sfnt/sfdriver.c,
src/sfnt/ttbdf.h, src/sfnt/ttbdf.c, src/sfnt/sfobjs.c:
Added support for an embedded 'BDF ' table within SFNT-based
bitmap font files. This is used to store atoms & properties from
the original BDF fonts that were used to generate the font file.
the feature is controled by TT_CONFIG_OPTION_BDF within 'ftoption.h'
and is used to implement FT_Get_BDF_Property for these font files.
At the moment, this is still experimental, the BDF table format isn't
cast into stone yet.
* docs/TODO: Add some bugs which should be fixed.
* include/freetype/internal/tttypes.h (TT_FaceRec): Add `glyf_len'
element.

heap-optimized embedded bitmap loader. This one also fixes bug #12107
* src/sfnt/sfobjs.c: fixed bug that prevented loading SFNT fonts without
a 'kern' table.
drastically reduce the heap usage of FreeType, especially in the case
of memory-mapped files. The idea is to avoid loading and decoding tables
in the heap, and instead access the raw data whenever possible (i.e.
when it doesn't compromise performance).
This had several impacts: first, opening vera.ttf uses a ridiculous amount
of memory (when the FT_Library footprint is accounted for), until you start
loading glyphs. Even then, you'll save at least 20 Kb compared to the non
optimized case. performance of various operations, including open/close
has also been dramatically improved.
More optimisations to come. The auto-hinter eats memory like crazy? This
must be stopped...
src/truetype/ttpload.c, src/truetype/ttpload.h, src/truetype/ttgload.c:
added the temporary configuration FT_OPTIMIZE_MEMORY to control various
optimizations used to reduce the heap footprint of memory-mapped TrueType
files.
* src/truetype/ttpload.c (tt_face_load_loca, tt_face_get_location,
tt_face_done_loca): when FT_OPTIMIZE_MEMORY is set, the locations table
is read directly from memory-mapped streams, instead of being decoded
into the heap.
* src/truetype/ttpload.c: only load the CVT and fpgm tables when the
bytecode interpreter is compiled in.
* src/pcf/pcfutil.c: Use FT_LOCAL_DEF.
* src/pcf/pcfutil.h: Include FT_CONFIG_CONFIG_H.
Use FT_BEGIN_HEADER and FT_END_HEADER.
Use FT_LOCAL.

include/freetype/internal/psnames.h (removed),
include/freetype/internal/internal.h (FT_SERVICE_POSTSCRIPT_NAMES):
added new service to handle glyph name dictionaries, replacing
the old internal header named "psnames.h" by "services/svpsname.h"
note that this is different from "services/svpostnm.h" which only
handles the retrieval of Postscript font name for a given face.
(should we merge these two services into a single header ??)

FT_FACE_FIND_GLOBAL_SERVICE (used to lookup a service globally,
instead of only within the current module)

heavy internal modifications to introduce the concept of

get rid of various numbers of hacks.

include/freetype/internal/ftobjs.h, include/freetype/internal/tttypes.h,

changed the name of TT_CONFIG_OPTION_COMPILE_UNPATENTED_HINTING to
the simpler TT_CONFIG_OPTION_UNPATENTED_HINTING
removed the macro TT_CONFIG_OPTION_FORCE_UNPATENTED_HINTING. Instead,
the same effect can be used by setting a debug-hook with
FT_DEBUG_HOOK_UNPATENTED_HINTING globally with FT_Set_Debug_Hook()
the SFNT loader to check for SFNT-based font files differently. We now
ignore the range "helper" fields and check the "head" table's magic
number instead.
src/sfnt/sfobjs.c, src/sfnt/sfdriver.c, src/base/ftnames.c:
fixing the SFNT name table loader to support various buggy fonts.
it now ignores empty name entries, entries with invalid pointer
offsets and certain fonts containing tables with broken "storageOffset"
fields.
name strings are now loaded on demand, which reduces the memory
requirements for a given FT_Face tremendously (for example, the
name table of Arial.ttf is about 10Kb and contains 70 names !!)
finally, this is a _quick_ fix. The whole name table loader and
interface will be rewritten in a much more cleanly way shortly,
once CSEH have been introduced in the sources.

- created "builds/devel" to hold developer builds options
for both Win32 and Unix
- fixed a bug in the winfonts driver, where the glyph image format
wasn't set correctly..
I've made a few modifications:
- there is no new field named "driver" in "FT_SizeRec"
- the new fields in "TT_SizeRec" are:
strike_index :: value 0xFFFF means "no sbit strike selected"
strike_metrics :: the FT_Size_Metrics structure corresponding to
the currently selected strike
- the code in "ttload.c" has been somewhat cleaned up too
thanks a lot, Y-U !!
