commit 119a9bf8c474ec8d7db11235f90a3e266c911e1e

    Bug 1493: Enhance Text/ASS subtitle layout: Split too wide text into multiple lines (max 4) fitting into box, trimming it beforehand
    Not always are Text/ASS subtitles well formed with newline character.
    Use new StringUtil to re-layout if their width doesn't fit into the box,
    by trimming all whitespace and splitting them into up-to 4 lines.
