Documentation for HB_GLYPH_FLAG_UNSAFE_TO_BREAK.
...
HB_GLYPH_FLAG_UNSAFE_TO_BREAK means that the glyph with this flag is somehow affected by the previous logical glyph (the previous index in the buffer if ltr and the next index if the buffer is rtl). If these two glyphs are separated by a break (line or otherwise) then the underlying text should be re-shaped on both sides up to corresponding position in the text of some glyph not marked with this flag.

At any position, if state is not zero, mark unsafe-to-break before,

At any position, if there's an action entry for end-of-text, mark
unsafe to break.
Also changes buffer diff impl to allow for flag differences as long
as the buffer glyph flags are superset of reference glyph flags.
With this, all MORX tests pass.

Ouch! Missing coords should still be evaluated as coord=0, which
most of the time results in a factor of 0. We were skipping these,
which was equivalent to a factor of 1.

Improve CGJ skipping logic
...
Previously we made CGJ unskippable. Now, if CGJ did NOT prevent
any reordering, allow skipping over it. To make this work we
had to make changes to the Arabic mark reordering algorithm
implementation to renumber moved MCM marks. See comments.

atomics: Favor compiler primitives over macOS APIs. ( #676 )

In macOS 10.12, the `OSMemoryBarrier` and related APIs were deprecated
in favor of using `std::atomic`. On the way to supporting `std::atomic`,
we can favor using the "Intel primitives" which are also available on
macOS.

[collect_glyphs] Bail if input data looks like garbage
...
Specificaly, when a range or sorted array has unexpected order, we take that as
font data being garbage and bail out. This fixes significant slowdown on a bad
version of Chandas font which has a 600KB GPOS with garbage inside.
Later on, I like to add a maximum-work counter for collect_glyphs to protect
against malicious fonts as well.
