抽象The type of event.
可选data: any(Optional) Data to pass to the callback. If multiple parameters p1, p2, p3, ... need to be passed, use an array structure such as [p1, p2, p3, ...]. If a single parameter p needs to be passed and p is an array, use a structure such as [p]. For other single parameters p, you can directly pass parameter p. If data is Event.EMPTY, it means passing an Event object to the callback function. Note that it is not passing Event.TEMP, but an independent Event object.
True if there are listeners for this event type, false otherwise.

Filterclass is the base class for filters. Filters are post-processing operations on nodes, so they inevitably operate on a renderTexture.Zh
Filter 是滤镜基类。滤镜是针对节点的后处理过程,所以必然操作一个rendertexture
