Khaled Hosny 2452543fdd [ot] Fix automatic fraction for RTL scripts (#405) 
The numbers for right-to-left scripts are processed also from right to
left, so the order of applying “numr” and “dnom” features should be
reversed in such case.

No one else should care!

Behdad Esfahbod 7cf9952e7f [USE] Remove non-canonical decompositions 
We have had added this in Indic shaper to assist shaping these scripts.
In Universal Shaping Engine however, it is up to font designer to
decompose them.  Hence moving them from Indic shaper to USE was
wrong.

Behdad Esfahbod 6cff753941 Remove Tibetan decomposition rules from Indic shaper 
The decomposition is very obscure and unlikely to help
any fonts.  Just remove it since Uniscribe probably doesn't
do this either.

Behdad Esfahbod c4ca49d55b Revert "[indic] Remove redundant Chakma decomposition rule" 
This reverts commit 805f76fc00.

Need to investigate why having this rule (with the reversed order)
fixes decomposition as reported by punchcutter:

anymore.

nvelinov 7d1c5d8281 Compilation Error for ASSERT_STATIC on Some Compilers (#380) 
* this pointer in type definitions is not interpreted as a constant.
This rule is not enforced strictly by all compilers, but the Green Hills Software compiler will regard this as an error.

* Merging branches for the DEFINE_SIZE_UNION macro
Adding check for the existence of static_size field in the tested member.

Behdad Esfahbod e2b878055b Disable OTL processing for Hebrew if GPOS doesn't have Hebrew subtable 
New approach to fix this:
69f9fbc420

Previous approach was reverted as it was too broad.  See context:
https://github.com/behdad/harfbuzz/issues/347#issuecomment-267838368

With U+05E9,U+05B8,U+05C1,U+05DC and Arial Unicode, we now (correctly) disable
GDEF and GPOS, so we get results very close to Uniscribe, but slightly different
since our fallback position logic is not exactly the same:

Before:		[gid1166=3+991|gid1142=0+737|gid5798=0+1434]
After:		[gid1166=3+991|gid1142=0@402,-26+0|gid5798=0+1434]
Uniscribe:	[gid1166=3+991|gid1142=0@348,0+0|gid5798=0+1434]
