Simon Hausmann	f1fb451791	Make the line break iterators implement Clone ... This is needed in the future to be able to roll back state within the line breaking when we can't fit even a single word into the line and have to go back to fitting glyph by glyph. For the unicode line break iterator the clone is a little more complicated. The iterator is clone, but the type is anonymous. I first had an implementation to moved the iterator into a closure, which was cloned via another control closure. But that's complicated and still involves allocating the various bits & pieces the closure captures. So instead the simpler solution used here is to allocate the breaks into a shared vector.	2022-05-13 17:33:01 +02:00
Simon Hausmann	4765cd3c40	Fix inconsistency in line break iterators ... The unicode linebreak iterator always produces a mandatory break at end of text. This is not only confusing, but also inconsistent with the simple line break iterator and with trailing spaces it could cause the line break algorithm to emit empty lines at the end of text.	2022-05-13 17:33:01 +02:00
Simon Hausmann	1d1b13e4d6	Clean up line break "abstraction" ... Use unicode-linebreak's enum directly and ony use a custom enum in the fake module.	2022-03-10 10:51:32 +01:00
