But while you're here could you please try to explain the following issues wrt three members of glyph_row: - short used[1 + LAST_AREA]: What does "Number of glyphs actually filled in areas." mean? Does this mean that for example the first element is zero when the left margin doesn't exist? - int x, y: Where and how are these set for a particular row (including header- and mode-line) and when and how are these eventually consumed? This is the greatest mystery for me so far. - int visible_height: "Partially visible rows may be found at the top and bottom of a window." Is it true that we can draw partially visible rows at the top of the window? Thanks, martin
