gui_toolkit 0.97.0

Changed

• ui.find_sweep (breaking): a find in a lazy column reads the column a slice of items at each frame (FIND_SWEEP_ITEMS), from the top down, instead of building all of it in one frame: a long document no longer freezes the window when a needle rests. It returns the items this build makes for it, given to ui.lazy_begin(sweep = ...) (was lazy_begin(all = find_sweep())); the text of the scope around the items (the column's own boxes, before them and after them) is read too, in reading order. Until a sweep ends, what the last one found stands; ui.find_progress says how far it is, and find_count while find_pending is what it has read so far. A match not counted yet has the index -1.
