Behdad Esfahbod 029a82d81d [hangul] Apply *jmo features to all Hangul chars
This is what old HB does.  Morever, fixes rendering with Win8 malgun
font.  The Win7 version doesn't compose with either Uniscribe nor HB,
but Win8 version works as expected, like Uniscribe, with this change.

Lets call Hangul done for now.

Behdad Esfahbod 41ae674f68 Don't create hb_apply_context_t per glyph!
I couldn't measure significant performance gains out of this; maybe
about 5% (with one million Malayalam strings).  Still, not bad.
But reminds me that optimizing this codebase without profiling first
is simply not going to work.  Oh well...

That's not in the OpenType spec, but it's what MS and Adobe do.

Behdad Esfahbod c9a841f445 Add simple Hangul shaper that recomposes Jamo when feasible
Previously, we were NOT actually recomposing Hangul Jamo.  We do now.
The two lines in:

test/shaping/texts/in-tree/shaper-default/script-hangul/misc/misc.txt

Now render the same with the UnDotum.ttf font.  Previously the second
linle was rendering boxes.

We can also start applying OpenType Jamo features later.  At this time,
I have no idea how the 'ljmo', 'vjmo', 'tjmo' features are supposed to
work.  Maybe someone can explain them to me?

Hangul.

Behdad Esfahbod 183224684a Use generic shaper for Buhid
As requested by Jonathan Kew.

We need to devise a better mechanism to choose which scripts to
pass through the Indic shaper.  Moreover, currently we are storing
data for some scripts in the Indic shaper that are not even going
through that shaper.  Need to find a better way...

Behdad Esfahbod bc71ad4973 Fix atomic-int op on Apple
The OSAtomicAdd32Barrier operator returns the new value, we want the
old value.

Behdad Esfahbod a1970d9afc Add support for atomic int and mutex on Apple systems
So, apparently there's no atomic int 'get' method on Apple.  You have to
add(0) to get.  And that's not const-friendly.  So switch inert-object
checking to a non-atomic get.  This, however, is safe, and a negligible
performance boost too.
