    Draws the given \a text in the specified \a rectangle using the
    provided \a painter and \a palette.

    Text is drawn using the painter's pen. If an explicit \a textRole
    is specified, then the text is drawn using the \a palette's color
    for the specified role.  The \a enabled value indicates whether or
    not the item is enabled; when reimplementing, this value should
    influence how the item is drawn.

    The text is aligned and wrapped according to the specified \a
    alignment.
