18 * Ncurses UI for telescope.
23 * ncurses allows you to scroll a window, but when a line goes out of
24 * the visible area it's forgotten. We keep a list of formatted lines
25 * (``visual lines'') that we know fits in the window, and draw them.
27 * This means that on every resize we have to clear our list of lines
28 * and re-render everything. A clever approach would be to do this
29 * ``on-demand'', but it's still missing.
