Better tracing of loaded glyphs.
Previously, the loading of a glyph was traced at level 4, if at all.
With this change, all font loading routines emit a tracing message
at level 1, making it easier to select tracing output (for example
using F2_DEBUG="any:1 afhints:7 aflatin:7").

[cff] Add a new Type 2 interpreter and hinter.
This work, written by Dave Arnold <darnold@adobe.com> and fully
integrated into FreeType by me, is a donation by Adobe in
collaboration with Google. It is vastly superior to the old CFF
engine, and it will replace it soon. Right now, it is still off by
default, and you have to explicitly select it using the new
`hinting-engine' property of the cff driver.
For convenience, (most of) the new files are committed separately.
* include/freetype/config/ftheader.h (FT_CFF_DRIVER_H): New macro.
* include/freetype/ftcffdrv.h: New file to access CFF driver
properties.
* include/freetype/fterrdef.h (FT_Err_Glyph_Too_Big): New error
code.
* include/freetype/internal/fttrace.h: Add `cf2blues', `cf2hints',
and `cf2interp'.
* src/cff/cffgload.h (CFF_SubFont): New member `current_subfont'.
* src/cff/cffobjs.h (CFF_DriverRec): New members `hinting_engine'
and `no_stem_darkening'.
* src/cff/cfftypes.h (CFF_FontRec): New member `cf2_instance'.
* src/cff/cff.c: Include new files.
* src/cff/cffdrivr.c (cff_property_set, cff_property_get): Handle
`hinting-engine' and `no-stem-darkening' properties (only the Adobe
engine listens to them).
* src/cff/cffgload.c: Include `cf2ft.h'.
(cff_decoder_prepare): Initialize `current_subfont'.
(cff_build_add_point): Handle Adobe engine which uses 16.16
coordinates.
(cff_slot_load): Handle FT_LOAD_NO_SCALE and FT_LOAD_NO_HINTING
separately.
Choose rendering engine based on `hinting_engine' property.
* src/cff/cffload.c (cff_font_done): Call finalizer of the Adobe
engine.
* src/cff/cffobjs.c: Include FT_CFF_DRIVER_H.
(cff_driver_init): Set default property values.
* src/cff/rules.mk (CFF_DRV_SRC, CFF_DRV_H): Add new files.

This is essentially a mechanical conversion, adding inclusion of

stand-alone compiling modes of the rasterizer modules.
To convert the remaining occurrences of FT_Err_XXX and friends it is
necessary to rewrite the code. Note, however, that it doesn't harm
if some cases are not handled since FT_THROW is a no-op.

Really fix Savannah bug #28678 (part 1).
After long discussion, we now consider the character width vector
(wx,wy) returned by the `sbw' Type 1 operator as being part of *one*
direction only. For example, if you are using the horizontal
writing direction, you get the horizontal and vertical components of
the advance width for this direction. Note that OpenType and CFF fonts
don't have such a vertical component; instead, the GPOS table can be
used to generate two-dimensional advance widths (but this isn't
handled by FreeType).
* include/freetype/ftincrem.h (FT_Incremental_MetricsRec): Add
`advance_v' field to hold the vertical component of the advance
value.
* src/truetype/ttgload.c (tt_get_metrics), src/cff/cffgload.c
(cff_slot_load), src/type1/t1gload.c

Improve vertical metrics calculation (Savannah bug #27364).
The calculation of `vertBearingX' is not defined in the OTF font
spec so FreeType does a `best effort' attempt. However, this value
is defined in the PDF and PostScript specs, and that algorithm is
better than the one FreeType currently uses:
FreeType: Use the middle of the bounding box as the X coordinate
of the vertical origin.
Adobe PDF spec: Use the middle of the horizontal advance vector as
the X coordinate of the vertical origin.
FreeType's algorithm goes wrong if you have a really small glyph
(like the full-width, circle-like dot at the end of the sentence, as
used in CJK scripts) with large bearings. With the FreeType
algorithm this dot gets centered on the baseline; with the PDF
algorithm it gets the correct location (in the top right). Note
that this is a serious issue, it's like printing the dot at the end
of a Roman sentence at the center of the textline instead of on the
baseline like it should. So i believe the PDF spec's algorithm
should be used in FreeType as well.
The `vertBearingY' value for such small glyphs is also very strange
if no `vmtx' information is present, since the height of the bbox is
not representable for the height of the glyph visually (the
whitespace up to the baseline is part of the glyph). The fix also
includes some code for a better estimate of `vertBearingY'.
* src/base/ftobjs.c (ft_synthesize_vertical_metrics): `vertBearingX'
is now calculated as described by the Adobe PDF Spec. Estimate for
`vertBearingY' now works better for small glyphs completely above or
below the baseline into account.
* src/cff/cffgload.c (cff_slot_load): `vertBearingX' is now
calculated as described by the Adobe PDF Spec. Vertical metrics
information was always ignored when FT_CONFIG_OPTION_OLD_INTERNALS
was not defined.
* src/truetype/ttgload.c (compute_glyph_metrics): `vertBearingX' is
now calculated as described by the Adobe PDF Spec.

* src/cff/cffgload.c (cff_decoder_parse_charstrings): No longer
assume that the first argument on the stack is the bottom-most
element. Two reasons:
o According to people from Adobe it is missing in the Type 2
specification that pushing of additional, superfluous arguments
on the stack is prohibited.
o Acroread in general handles fonts differently, namely by popping
the number of arguments needed for a particular operand (as a PS
interpreter would do). In case of buggy fonts this causes a
different interpretation which of the elements on the stack are
superfluous and which not.
Since there are CFF subfonts (embedded in PDFs) which rely on
Acroread's behaviour, FreeType now does the same.
