21 1d08c280 2021-03-06 op * ==============
23 1d08c280 2021-03-06 op * ncurses allows you to scroll a window, but when a line goes out of
24 1d08c280 2021-03-06 op * the visible area it's forgotten. We keep a list of formatted lines
25 1d08c280 2021-03-06 op * (``visual lines'') that we know fits in the window, and draw them.
27 1d08c280 2021-03-06 op * This means that on every resize we have to clear our list of lines
28 1d08c280 2021-03-06 op * and re-render everything. A clever approach would be to do this
29 970deec6 2021-04-24 op * ``on-demand'', but it's still missing.
