Behdad Esfahbod 30eed75de2 [shape-plan] Fix typo! 
The only effect is, if shaper_list was not NULL and no shaper was found,
we now don't insert anything into cache and return earlier.

Behdad Esfahbod fd0001d7db [coretext] Compare CGFont and PS name, if CTFont didn't match

Fixes vertical text.  CoreText backend is in very good shape now!

Behdad Esfahbod 5a0eed3b50 [coretext] Implement vertical shaping 
Currently doesn't work though, we detect font fallback.  Apparently
matching on ct_font is not safe for this.  Looks like commit
25f4fb9b56 wasn't enough after all.

non-monotone clusters.

Behdad Esfahbod b5fbc3b8f5 API: Do not clear buffer-flags in hb_buffer_clear_contents() 
After 763e5466c0, one doesn't
need to set flags for different pieces of text.  The flags now
are something the client sets up once, depending on how it
actually uses the buffer.  As such, don't clear it in
clear_contents().

Tests updated.

Behdad Esfahbod 5ec45dd37c [coretext] Minor 
It's hard to handle all possible NULL returns from CoreText.  Add one
more...

Behdad Esfahbod 624a299b82 [coretext] Attach marks to base clusters 
Fixes https://githu.com/behdad/harfbuzz/issues/49
to the extent that it can be fixed.
 2014-08-11 15:29:18 -04:00
Behdad Esfahbod 3c41ccb535 [coretext] Use input clusters 
Before, this shaper was returning UTF-16 cluster indices instead of
returning whatever cluster values the user had had set up in the buffer.
Ouch!

Behdad Esfahbod a6b8dc8742 [coretext] Fix buffer resize handling 
We can't really resize buffer and continue in this shaper as we are
using the scratch buffer for string_ref and log_cluster.  Restructure
shaper to retry from (almost) scratch.

Behdad Esfahbod b9993d8d6d [coretext] Fix assert on Yosemite 
Apparently those functions documented as sometimes returning NULL
actually exercise that right in OS X 10.10 Yosemite.  The scratch
was too small for that.  I *think* I fixed it, but haven't tested
as I don't have Yosemite.

Behdad Esfahbod 38fb30d742 Use atexit() only if it's safe to call from shared library 
Apparently they are not (advertised as?) safe on BSD systems.
We ignore the case of static libraries.
