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.
