| 560 | * deferred transaction?) but this is an important legacy use case, for example moving |
| 561 | * a window at the same time it draws makes use of this kind of technique. So anyway |

| 566 | * DeferTransactionUntil -> frameNumber = 2 |

| 569 | * Now imagine getHeadFrameNumber returned mDrawingState.mFrameNumber (or mCurrentFrameNumber). |
| 570 | * Prior to doTransaction SurfaceFlinger will call notifyAvailableFrames, but because we |
| 571 | * haven't swapped mCurrentState to mDrawingState yet we will think the sync point |
| 572 | * is not ready. So we will return false from applyPendingState and not swap |
| 573 | * current state to drawing state. But because we don't swap current state |
| 574 | * to drawing state the number will never update and we will be stuck. This way |
