Remain issue

Whether highlight/downplay will effect all the subtree or only the hovered node?
There are both scenarios, depending on the styles the treemap used. For example,
a treemap uses border to distinguish the highlighted subtree, we should only
highlight the target node rather than the entire subtree. Otherwise the all of the
border inner the subtree will be highlighted unexpectedly. If a treemap uses area
color to distinguish the highlighted subtree, the entire subtree needed to be

But I only support "highlight single node" here. Because based on the current
mechanism, implement "highlight entire subtree" need some more code, a little
like focusNodeAdjacency in graph series, and event more complicated because
the zrender elements in treemap are nested so we need to consider a mouse over
listener should/should not listen to its descendent.
