Returns a list of gtk.TextTag that are toggled on or off at this
point. (If toggled_on is TRUE, the list contains tags that are
toggled on.) If a tag is toggled on at iter, then some non-empty
range of characters following iter has that tag applied to it. If
a tag is toggled off, then some non-empty range following iter
does not have the tag applied to it.
