Extract a renderLines function

Browse source 
We'll make some changes to how the display strings are rendered, so it helps to
have this code only once. This also fixes the problem that contexts using
refreshViewportOnChange weren't able to use column alignments so far. We didn't
need this yet, but it's just nice if everything works. :)
