* position carries the
* #HB_GLYPH_FLAG_UNSAFE_TO_BREAK or when
* hyphenation or other text transformation
* happens at line-break position, in the following
* way:
* 1. Iterate back from the line-break position
* until the first cluster start position that is
* NOT unsafe-to-concat, 2. shape the segment from
* there till the end of line, 3. check whether the
* resulting glyph-run also is clear of the

* if it is, just splice it into place and the line
* is shaped; If not, move on to a position further
* back that is clear of unsafe-to-concat and retry
* from there, and repeat.
* At the start of next line a similar algorithm can
* be implemented. That is: 1. Iterate forward from
* the line-break position untill the first cluster
* start position that is NOT unsafe-to-concat, 2.
* shape the segment from beginning of the line to
* that position, 3. check whether the resulting
* glyph-run also is clear of the unsafe-to-concat
* at its end-of-text position; if it is, just splice
* it into place and the beginning is shaped; If not,
* move on to a position further forward that is clear
* of unsafe-to-concat and retry up to there, and repeat.
* A slight complication will arise in the
* implementation of the algorithm above,
* because while our buffer API has a way to
* return flags for position corresponding to
* start-of-text, there is currently no position
* corresponding to end-of-text. This limitation
* can be alleviated by shaping more text than needed
