start thinking of compute_fragments as a detail
I think all we need to maintain is the populate_screen_line_starting_pos array. It's easy to render screen lines one by one from it, and we'll only ever construct one additional screen line at a time. I'd hoped to delete other calls to Text.populate_screen_line_starting_pos, but it turns out we need to update it when editing sometimes. Give up on that for now; it's a no-op if not needed.
