Behdad Esfahbod 2e193b240e [Indic] Don't split U+0AC9 
Althought IndicMatraCategory.txt classifies it as Top_And_Right matra,
it does not have Unicode decomposition, and Uniscribe does not do
anything special about it either.

Gujarati failures down from 0.672% to 0.0130966%.

Behdad Esfahbod 8c973ebf0f [Indic] Implement per-script matra positioning 
Following what the spec says.

Brings down Telugu failures from 40% to 3.75%, and Kannada failures from
44% to 10%.  Does NOT affect other scripts' test results.

Behdad Esfahbod b01d9b3d90 [Indic] Disallow decomposition of a couple characters 
This is a hack for now.  Will be fixed when we do complex-shaper-driven
normalization properly.

The results with or without decomposition are the same, but Uniscribe
does not normalize, so this matches better.

Behdad Esfahbod 91cade7555 [Indic/Unicode] Decompose Sinhala split matras the way Uniscribe likes 
Makes no visual difference.

Fixes most of the failures.  Down from 15% to 1.3%!

Behdad Esfahbod d487fff266 Split matras without a Unicode decomposition 
This is a hack for now, to get us going with Khmer.  This will be
refactored properly later to move the complex logic into complex
shapers.

Behdad Esfahbod 33ccc77902 [API] Make set_user_data() functions take a replace parameter 
We need this to set data on objects safely without worrying that some
other thread unsets it by setting it at the same time.

Behdad Esfahbod c605bbbb6d Remove C++ guards from source files 
Where causing issues for people with MSVC.

Behdad Esfahbod ffd4a436f7 Add tests for compose()/decompose() 
Adjust glib fallback implementation.

The tests are not hooked up for ICU yet.

Behdad Esfahbod 22fdc66712 [glib] Add compose() and decompose() implementations with fallback 2011-07-20 21:51:37 -04:00
Behdad Esfahbod c4641723fb [API] Add compose() and decompose() unicode funcs, rename other ones 
Add compose() and decompose() unicode funcs.  These implement
pair-wise canonical composition/decomposition.

The glib/icu implementations are lacking for now.  We are adding
API for this to glib, but I cannot find any useful API in ICU.
May end of implementing these in-house.

Changed all unicode_funcs callback names to remove the "_get" part.
Eg, hb_unicode_get_script_func_t is now hb_unicode_script_func_t,
and hb_unicode_get_script() is hb_unicode_script() now.

Behdad Esfahbod 891c4755ba Humm, undo some shuffling 
In preparation for adding more advanced unicode funcs.

Behdad Esfahbod c57d454acc Rename all private sources and headers to C++ files 
So we can liberally use the simple features of C++ that parts of the
codebase is already using.

Behdad Esfahbod af02933739 [API] Remove hb_*_get_reference_count() 
This was a bizzare piece of API that I inherited from cairo.  It has
been wrong adding them to cairo in the first place.  Remove them before
someone uses them!
