Behdad Esfahbod 7f9e7f8689 Adjust normalizer for out-of-order marks 
We are going to implement Unicode Arabic Mark Ordering Algorithm:

  http://www.unicode.org/reports/tr53/tr53-1.pdf

which will reorder marks out of their sorted ccc order.  Adjust
normalizer to stop combining as soon as dangerous ordering is
detected.

Behdad Esfahbod 9786fcd8fd Fix GPOS v_origin ordering 
This should affect mark attachment in vertical text.  I have no font to test,
but this sounds the right order.

Behdad Esfahbod 5d98de1f38 Tweak mark-base attachment 
Apparently a base glyph can also become an attached component of a
ligature if the ligature-forming lookup used IgnoreBase.  This was
being confused with a non-first component of a MultipleSubst and
hence not matched for mark-attachment.  Tweak test to fix.

Behdad Esfahbod c44657a05d Tweak input matching some more 
Followup to 8b2c94c43f

Allow matching sequences of marks attached to different ligatures,
as supposedly the base of the subsequent marks were already jumped
over.

Before 71c0a1429d GURMUKHI used to be at 15,
because Uniscribe seems to allow this character standalone, but that looks
wrong.

Behdad Esfahbod 8b2c94c43f Tweak ligature component matching for ligature formation 
If two marks want to ligate and they belong to different components of the
same ligature glyph, and said ligature glyph is to be ignored according to
mark-filtering rules, then allow.

Example Burmese senquence:

  U+1004,U+103A,U+1039,U+101B,U+103D,U+102D

Test font provided by Norbert Lindenberg.

This is a temporary hack just to avoid incorrect shaping results, pending proper support
