Add a new header named FT_ADVANCES_H declaring some new APIs
to extract the advances of one or more glyphs without necessarily
loading their outlines. Also provide 'fast loaders' for the
TrueType, Type1 and CFF font drivers (more to come later)
* autogen.sh: add checks for minimum version of the 'autotools'
stuff.
Pass dropout rules from the TT bytecode interpreter to the
rasterizer; temporarily this is enabled only if
`USE_SCAN_CONVERSION_RULES' is defined.
* include/freetype/ftimage.h (FT_OUTLINE_SMART_DROPOUTS,
FT_OUTLINE_EXCLUDE_STUBS): New flags for for FT_Outline.
* src/raster/ftraster.c (Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
Horizontal_Gray_Sweep_Drop): Use same mode numbers as given in the
OpenType specification.
Fix mode 4 computation.

[USE_SCAN_CONVERSION_RULES]: Convert scan conversion mode to
FT_OUTLINE_XXX flags.

(TT_Hint_Glyph): This function.
Hinting instructions for a composite glyph apparently refer to the
just hinted subglyphs, not the unhinted, unscaled outline. This
seems to fix Savannah bugs #20973 and (at least partially) #23310.
expanded). This is needed for options like
--includedir='${prefix}/include'.
* builds/unix/detect.mk, configure: Prevent argument expansion in
call to the (real) `configure' script.
* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation if
TT_USE_BYTECODE_INTERPRETER isn't defined.
There exist CFFs which contain opcodes for the Type 1 operators
`hsbw' and `closepath' which are both invalid in Type 2 charstrings.
However, it doesn't harm to support them.
* src/cff/cffgload.c (CFF_Operator): Add `cff_op_hsbw' and
`cff_op_closepath.'
(cff_argument_counts): Ditto.
(cff_decoder_parse_charstrings): Handle Type 1 opcodes 9 (closepath)
and 13 (hsbw) which are invalid in Type 2 charstrings.
recursion depth of 1. This was the maximum value in TrueType 1.0,
and some older fonts don't set this field correctly.

(gxv_mort_subtable_type1_substTable_validate): Fix tracing message.
number of points in contours. Problem reported by Victor Stinner
<victor.stinner@haypocalc.com>.
(TT_Process_Simple_Glyph): Synchronize variable types.
* src/truetype/ttgload.c (tt_loader_init): Re-execute the CVT
program after a change from mono to grayscaling (and vice versa).
Use correct constant for comparison to get `exec->grayscale'.

this is a major patch used to drastically improve the performance
of loading glyphs. This both speeds up loading the glypn vector
themselves and the auto-fitter.
note that we've started using inline assembler with GCC to
implement FT_MulFix, given that this function is so damn
important for the engine's performance.
the resulting speed-up is about 25%.
return error if table is missing.
Check table length in non-FT_OPTIMIZE_MEMORY'ed `tt_face_load_hmtx'.
* src/sfnt/sfobjs.c (sfnt_load_face): Take care of missing metrics
tables. The last change makes Mac bitmap-only font not load and this
fixes it.
* src/truetype/ttgload.c (load_truetype_glyph): Fix compilation error
when FT_CONFIG_OPTION_INCREMENTAL is defined.
after the tables' tags; `hdmx' is TrueType-specific and thus the code
is moved to the truetype module; `get_metrics' is moved here from the
truetype module so that the code can be shared with the cff module.
This pass involves no real changes. That is, the code is moved
verbatim mostly. The only exception is the return value of
`tt_face_get_metrics'.

* src/sfnt/ttmtx.c, src/sfnt/ttmtx.h: Metrics-related tables' loading
and parsing code is moved here.
Move `tt_face_get_metrics' here from the truetype module. The return
value is changed from `void' to `FT_Error'.
* include/freetype/internal/fttrace.h: New trace: ttmtx.
* src/truetype/ttpload.c, src/truetype/ttpload.h: `hdmx' loading and
parsing code is moved here.
New function `tt_face_load_prep' splitted from `tt_face_load_fpgm'.
`tt_face_load_fpgm' returns `FT_Err_Ok' if `fpgm' doesn't exist.
* src/cff/cffgload.c, src/cff/cffobjs.c: Update.

* 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).
`load_strike_metrics' used to load the strike's metrics.
* src/sfnt/sfdriver.c, src/sfnt/ttsbit.c, src/sfnt/ttsbit.h,
src/sfnt/ttsbit0.c: New function `tt_face_load_strike_metrics'.

FNT driver.
Introduce new size selection interface.

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

- fixing apinames.c, adding support for Watcom and Borland compilers
- adding generation of exported symbols list to the build system, including the Unix one !!
sorry Werner, I have no time to document this in ChangeLog at the moment
