    treeview: Deprecated rules-hint · 0ed766ec

    The rules-hint property has always been a fairly bad application API, as
    it set some wrong expectations for the developers; deferring to the
    theme makes it impossible to design application reliably, and if this is
    a usability setting we should either impose this setting on every theme,
    or simply drop it.
    Our own default theme does not honour the zebra striping, which makes
    this function even more questionable.
    In practice, usability studies on zebra striping have demonstrated that
    alternating colors on a list it improves readability just as much as
    clear ruling between rows, or by visually differentiating the selected
    row. Zebra striping improves readability (or, at least, it does not
    hinder it) on static displays, like a table on paper or a document; on a
    dynamic display, like an application's UI, there are different
    strategies that yield similar, if not better, results.
