Behdad Esfahbod 3b7aa651b4 [docs] Improve UNSAFE_TO_BREAK docs 2018-02-09 15:43:20 -06:00
bungeman 671f0a7733 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.
