20 1d08c280 2021-03-06 op * Text scrolling
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.
26 1d08c280 2021-03-06 op * This way is easy to scroll: just call wscrl and then render the
27 1d08c280 2021-03-06 op * first/last line!
29 1d08c280 2021-03-06 op * This means that on every resize we have to clear our list of lines
30 1d08c280 2021-03-06 op * and re-render everything. A clever approach would be to do this
31 1d08c280 2021-03-06 op * ``on-demand''.
33 1d08c280 2021-03-06 op * TODO: make the text formatting on-demand.
