每次 Scheduler 的调度都会按以下顺序更新调度器的状态：

• ScheduleBeginImplFrameDeadline: 用于设定一个 Deadline，在该 Deadline 之前都允许触发 SEND_BEGIN_MAIN_FRAME 事件，在 Deadline 触发后就不再允许触发该事件。它会 Post 一个延迟的 OnBeginImplFrameDeadline 事件，如果该事件执行了表示已经到了 Deadline（状态机进入 INSIDE_DEADLINE 状态），它会设置一些状态禁止触发 BeginMainFrame，然后进行下一次调度，这些调度都是需要在 Deadline 状态才能执行的操作，可能调度到 DRAW_IF_POSSIBLE，这会触发 client 提交 CF 到 viz，也可能调度到其他状态比如 PREPARE_TILES 等，当然也可能调度到 NONE 状态，在进入 Deadline 之后的所有操作都完成之后，调度器会进入空闲状态 IDLE，此时就算退出 Deadline 了，后续就允许触发 SEND_BEGIN_MAIN_FRAME 事件了。
• PostPendingBeginFrameTask: 用于检测是否需要触发 SEND_BEGIN_MAIN_FRAME 事件，如果需要它会 Post HandlePendingBeginFrame 事件，该事件执行后会使状态机进入 INSIDE_BEGIN_FRAME 状态，随后调度器会在合适的时机触发 SEND_BEGIN_MAIN_FRAME 事件，这会调用 client 进行绘制，在 client 绘制完成之后会请求调度器执行提交 COMMIT 以及激活 ACTIVATE_SYNC_TREE。
• StartOrStopBeginFrames: 用于检测当前是否处于 IDLE 状态，如果是则将自己从 BFS 移除，否则则将自己 加入 BFS。如果调度器将自己从 BFS 上移除，则会进入” 休眠状态 “，此时不会调度器不会占用 CPU，如果后续外部需要更新显示的画面，可以通过 cc::Scheduler::SetNeedsBeginFrame () 来激活调度器（注意 cc 模块外可以通过 cc::LayerTreeHost::SetNeedsCommit () 来间接调用它，如果在 cc::Layer 中，则可以直接调用它的 SetNeedsCommit 成员函数，如果 cc::Layer 没有任何变化，只调用 SetNeddsCommit () 则不会激活调度器，必须有实际的变更或者标记区域 demaged）。

执行tile任务，运行在单独的Raster线程（在SingleThreadTaskGraphRunner中执行Raster操作）这会将DisplayItemList中保存的绘制操作执行真实的绘制,绘制到内存中,注意这里采用的是OnCopyRasterBufferProvider。

TODO: 需要调查为什么每次Draw操作之后都会触发Tiles操作。猜测可能是deadline的时候不管tiles操作是否完成，Draw操作都会被触发，所以每次在draw完了之后都要再次触发tiles操作，这有点说不通。
触发 tiles(raster) 操作，由于此时并没有画面需要tiles，因此这个动作没有明显的效果，注释掉这里的代码后也没有看到异常。

....此处省略了设置Deadline的过程

Deadline时间到，此时由于没有任务可做，scheduler会将自己从BFS的监听中移除，这会导致support也将自己从BFS的监听中移除，并停止BFS。这里可以看到如果画面不需要更新cc以及viz都不会占用CPU或者GPU。
