Werner Lemberg 766b822f4c [raster] Fix 5-levels grayscale output. 
This was broken since version 2.3.0.

* src/raster/ftraster.c (count_table): Use pre-2.3.0 values (which
were then computed dynamically).
(Vertical_Gray_Sweep_Step): Updated.

valgrind).

(FT_RASTER_OPTION_ANTI_ALIASING, DEBUG_RASTER): Dont' #undef, just
comment out.

Bram Tassyns 4694ea2b95 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.

Werner Lemberg 11cb8c36ed Use 16.16 format while parsing Type 1 charstrings. 
This fixes Savannah bug #26867.

Previously, only integers have been used which can lead to serious
rounding errors.

However, fractional values are only used internally; after the
charstrings (of either Type 1 or 2) have been processed, the
resulting coordinates get rounded to integers currently -- before
applying scaling.  This should be fixed; at the same time a new load
flag should be introduced, to be used in combination with
FT_LOAD_NO_SCALE, which indicates that font units are returned in
16.16 format.  Similarly, the incremental interface should be
extended to allow fractional values for metrics.

field.

Werner Lemberg 7227114043 Fix B/W rasterization of subglyphs with different drop-out modes. 
Normally, the SCANMODE instruction (if present) to set the drop-out
mode in a TrueType font is located in the `prep' table only and thus
valid for all glyphs.  However, there are fonts like `pala.ttf'
which additionally contain this instruction in the hinting code of
some glyphs (but not all).  As a result it can happen that a
composite glyph needs multiple drop-out modes for its subglyphs
since the rendering state gets reset for each subglyph.

FreeType collects the hinted outlines from all subglyphs, then it
sends the data to the rasterizer.  It also sends the drop-out mode
-- after hinting has been applied -- and here is the error: It sends
the drop-out mode of the last subglyph only; drop-out modes of all
other subglyphs are lost.

This patch fixes the problem; it adds a second, alternative
mechanism to pass the drop-out mode: For each contour, the
rasterizer now checks the first `tags' array element.  If bit 2 is
set, bits 5-7 contain the contour's drop-out mode, overriding the
global drop-out mode.

* include/freetype/ftimage.h (FT_CURVE_TAG_HAS_SCANMODE): New macro.

* src/truetype/ttgload.c (TT_Hint_Glyph): Store drop-out mode in
`tags[0]'.

* src/raster/ftraster.c (Flow_Up, Overshoot_Top, Overshoot_Bottom):
Use bits 3-5 instead of 0-2.
(New_Profile): Set the drop-out mode in the profile's `flags' field.
(Decompose_Curve): Check `tags[0]' and set `dropOutControl' if
necessary.
(Vertical_Sweep_Drop, Horizontal_Sweep_Drop,
Horizontal_Gray_Sweep_Drop, Draw_Sweep): Use the profile's drop-out
mode.
