然后，如果需要，绘制（软件或硬件）是如果需要的话，这并非总是如此（例如，在命中测试）。
Then, if required, rendering (either software or hardware) is done if required, which is not always the case (for example, when doing hit testing).
不可见的元素不参与命中测试并且不接收输入事件，即使鼠标放在该元素可见时的边界上也如此。
Elements that are not visible do not participate in hit testing and do not receive input events, even if the mouse is over the bounds where the element would be if were visible.
会为映射到命中测试条件的所有可视对象调用命中测试筛选器回调方法，从您指定的可视对象开始，一直向下延伸到可视化树的分支。
The hit test filter callback method is invoked for all the visual objects that map to the hit test criteria, starting from the visual you specify and descending through its branch of the visual tree.
