LATEST CHANGES BETWEEN 2.1.1 and 2.1.0
LATEST CHANGES BETWEEN 2.1.3 and 2.1.2
I. IMPORTANT BUG FIXES
- FT_Vector_Transform had been incorrectly modified in 2.1.2, resulting
in incorrect transformations being applied (for example, rotations
were processed in opposite angles).
- the format 8 and 12 TrueType charmap enumeration routines have been
fixed (FT_Get_Next_Char returned invalid values)
- the PFR font driver returned incorrect advance widths when the
outline and metrics resolution defined in the font file were
different
- FT_Glyph_To_Bitmap now returnes succesfully when called with
a FT_BitmapGlyph argument (it previously returned an error)
- A bug in the Type 1 loader that prevented valid font bounding
boxes to be loaded from multiple master fonts.
- the SFNT validation code was rewritten. FreeType can now load
"broken" fonts that were usable on Windows, but not with previous
versions of the library
- the computation of bearings in the BDF driver has been fixed
II. MISCELLANEOUS
- the automatic and postscript hinters have both been updated. This
results in a relatively important increase of rendering quality
since many nasty defaults have been supressed.
- a new, experimental, support for incremental font loading (i.e.
loading of fonts where the glyphs are not in the font file itself,
but provided by an external component, like a Postscript interpreter)
has been added by Graham Asher. This is still work in progress
however.
- a new, experimental, path stroker has been added. It doesn't suffer
from sever rounding errors, and treat bezier arcs directly. Still
work in progress
- the massive re-formatting of sources and internal re-design is still
under-way. Many internal functions, constants, and types have been
renamed.
- the "load_flags" parameter of FT_Load_Glyph is now a FT_Int32
(instead of just being an FT_Int). This breaks source and binary
compatibility for 16bit systems only, while retaining both of them
for 32 and 64 bit ones.
some new flags have been added consequently:
FT_LOAD_NO_AUTOHINT :: disable the use of the auto-hinter
(but not native format hinters)
FT_LOAD_TARGET_NORMAL :: hint and render for normal anti-aliased
displays
FT_LOAD_TARGET_MONO :: hint and render for 1-bit displays
FT_LOAD_TARGET_LCD :: hint and render for horizontal RGB or BGR
sub-pixel displays (like LCD screens).
THIS IS STILL EXPERIMENTAL
FT_LOAD_TARGET_LCD_V :: same a FT_LOAD_TARGET_LCD, for vertical
sub-pixel displays (like rotated LCD screens)
THIS IS STILL EXPERIMENTAL
FT_LOAD_MONOCHROME is still supported, but only affects
rendering, not the hinting.

a new face was opened (with the FT_CONFIG_OPTION_USE_CMAPS options
enabled), causing many applications to not be able to display text
correctly with the 2.1.x releases.
- The PFR driver had a bug in its composite loading code that produces
incorrectly placed accents with many fonts.
- The Type42 driver crashed sometimes due to a nasty bug.

- The cache sub-system has been optimized in important ways. Cache hits
are now significantly faster. For example, using the CMap cache is

about twice faster than calling FT_Get_Char_Index on most platforms.
Similarly, using an SBit cache is about five times faster than loading
the bitmaps from a bitmap file, and 300 to 500 times faster than
generating them from a scalable format.
