Code Issues 4 Releases Wiki Activity

* src/base/ftoutln.c (FT_Outline_Embolden): Strength should be 

halved.

* src/base/ftsynth.c (FT_GlyphSlot_Embolden): Change the default
strength.
Don't increase slot->advance.y.



* include/freetype/freetype.h (FREETYPE_MINOR): Set to 2.
(FREETYPE_PATCH): Set to 0.

* builds/unix/configure.ac (version_info): Set to 9:9:3.
Currently, we are still binary compatible.

* builds/win32/visualc/index.html,
builds/win32/visualc/freetype.dsp,
builds/win32/visualc/freetype.vcproj: s/219/2110/, s/2.1.9/2.1.10/.

* builds/freetype.mk (refdoc), README, Jamfile (RefDoc):
s/2.1.9/2.1.10/.

* docs/CHANGES, docs/VERSION.DLL: Updated.

* ChangeLog: Split off older entries into...
* ChangeLog.20, ChangeLog.21: These new files.



The next release will be 2.2.0, so don't worry about source code
backwards compatibility.

* include/freetype/ftimage.h (FT_Outline_MoveToFunc,
FT_Outline_LineToFunc, FT_Outline_ConicToFunc,
FT_Outline_CubicToFunc, FT_SpanFunc, FT_Raster_RenderFunc),
include/freetype/ftrender.h (FT_Glyph_TransformFunc,
FT_Renderer_RenderFunc, FT_Renderer_TransformFunc): Decorate
parameters with `const' where appropriate.



* src/sfnt/ttsbit.c (tt_face_load_sbit_image): Compute vertBearingY
to make glyphs centered vertically.

* src/truetype/ttgload.c (compute_glyph_metrics): Compute
vertBearingY to make glyphs centered vertically.
Fix some bugs in vertical metrics:

  . loader->pp3.y and loader->pp4.y are in 26.6 format, not in font
    units.
  . As we use the glyph's cbox to calculate the top bearing now
    there iss no need to adjust `top'.



* src/otvalid/otvcommn.h (OTV_OPTIONAL_TABLE): Use FT_UShort to be
in sync with OTV_OPTIONAL_OFFSET.  Reported by YAMATO Masatake.


* docs/release: Update.
