And I miss probably knowledge of some built-in functions. In this below for now degraded function I do not know how to enlarge the font so that the (window-width) and (window-height) also change, so that I can get realistic numbers which I can use to center lines. What does not work: - enlarging font, I don't know how to enlarge it, so that width and height of window is adjusted to new enlarged font - centering, I am trying to center line by using window-width and setting fill-column, it seem it does not center nicely.
