Fix hiccups when doing canvas actions

Problems:

1. The final write should be atomic. That is, for the GUI thread the shapes can be observed either in the initial state or in the final state. No intermediate states should be observable (including during the write-back itself). 1.1) theoretically, it could be implemented by adding a lock to a shared d-pointer, but it doesn't guard from hierarchy action. 1.2) we could declare that locking the topmost shape would block hierarchy, but to get this topmost shape we should iterate through this hierarchy, which is unsafe
2. After the swap operation GUI thread might still have pointers to the old shapes that we replaced. How to fix that?
3. After swap operation, the shapes should emit some signals, so that layer's shape manager and other receivers get their notifications. How to postpone/duplicate these signals?
