f47a60a754 Mark UnsizedArrayOf<> as UNBOUNDED 
Since min_size is 0, Null() still accepts this type.

62890dee18 [aat] Zero mark advances if decided so even if there's cross-kerning 
Cross-kerning can only take care of positioning vertically.  It doesn't
adjust mark advance...

a201fa74cd [aat] Tweak fallback positioning logic when applying morx 
Such that for Indic-like scripts (eg. Khmer), we don't do any fallback mark
advance-zeroing / positioning, but we do for Latin, etc.  Reuses preferences
of our script-specific OpenType shapers for those.

Fixes regression: https://github.com/harfbuzz/harfbuzz/issues/1393
Which means, fixes again: https://github.com/harfbuzz/harfbuzz/issues/1264

b96ecb9971 More 
This makes more of the gcc spurious warning:

../../src/hb-null.hh:53:39: warning: enum constant in boolean context [-Wint-in-bool-context]

But not going to let that defeat correct code.  Type to switch to clang
as my main compiler...
