At the time that syntax highlighting DOM was introduced, the offsets of selection ranges had been broken. In change [1] Kasper fixed this for GR-DIFF-HIGHLIGHT with selection normalization functions. However, selections for copying code as implemented in GR-DIFF-SELECTION were still un-normalized. With this change, the normalization functionality introduced in [1] is moved to a JS library so that it can be used by both components. Tests are updated.
