Behdad Esfahbod 1827dc208c Add hb_ot_shape_glyphs_closure()

Behdad Esfahbod 585b107cde Add test caes for a minority language using Bengali
U+0985 BENGALI LETTER A followed by U+09D7 BENGALI AU LENGTH MARK.
According to Bobby de Vos on the mailing list, this results in a dotted
circle with most shaping engines, but is a legitimate sequence in this
minority language.

We reached the consensus on the list to NOT implement dotted-circle
in HarfBuzz.

Behdad Esfahbod 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.

As was reported to me, glib-mkenum does not understand named enums,
so remove for now.

Behdad Esfahbod 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.

Behdad Esfahbod 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.

Behdad Esfahbod 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.

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

Behdad Esfahbod 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.
