Khaled Hosny b68fba4dc8 [test] Use glyph ids instead of forcing ft funcs
We were using ft funcs because these are CFF fonts, but we can avoid
glyph names instead and keep testing both ot and ft.

We don't need to test the actual flag values.  For unsafe-to-break,

I simply removed the composite glyph and use the referenced simple
glyph directly.

Khaled Hosny 70137e2b4b [test] We don’t care about glyph positions here
Freetype and OT font functions give different positions for some glyphs
in this font (OT seems to be correct), but that is not what we are
interested in in this test.

Behdad Esfahbod 81e2b9b8a9 Never skip over CGJ
We might want to tweak this some more.  For now, never skipping over
it is better behavior than always skipping.

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.

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

I like to have a mode where CONTAINS_NOTDEF and CONTAINS_DOTTEDCIRCLE are not

of the six tests failing with --verify in test/shaping/run-tests.sh.
