a5f1834f57 Apply 'liga' for vertical writing mode too 
Apparently that's what Kazuraki uses to form vertical ligatures,
which suggests that it's what Adobe does.

5e88aa6682 Remove public enum names again 
As was reported to me, glib-mkenum does not understand named enums,
so remove for now.

4bf90f6483 Make HB_DIRECTION_INVALID be zero 
This changes all the HB_DIRECTION_* enum member values, but is
nicer, in preparation for making hb_segment_properties_t public.

69b84a8f6c Fix hb-view surface size calc for vertical text 
For some reason it doesn't quite work with IranianNastaliq, but
that looks like a font issue.

6bd9b479b8 Hide backend-specific shape functions 
Also remove shaper_options argument to hb_shape_full().  That was
unused and for "future".  Let it go.

More shaper API coming in preparation for plan/planned API.

c6035cf802 Add names to enums 
gdb was showing <anonymous enum> instead of useful stuff, so name
all our enums.

d1c9eb458c Make it an error to include non-top-level headers 
Users should #include <hb.h> (or hb-ft.h, hb-glib.h, etc), but
never things like hb-shape.h directly.  This makes it easier to
refactor headers later on without breaking compatibility.

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.

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...

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?
