Implementation of collapse

[ppiecuch]

Hi, I working on c++ implementation of your great Destructible (https://github.com/ppiecuch/godot/blob/master/modules/gdextensions/scene/destructible_sprite.cpp) and would like to also implement collapse functionality. I see that it has been started in new_destruction branch but I have a feeling that it is still work in progress. But maybe you could share idea how do you plan to implement this?
