Struct LayerChange 

pub struct LayerChange(/* private fields */);

A number a layer takes when it is made and whenever it or a layer beneath it changes, as its raster cache hashes are forgotten: a renderer that kept what it built from a subtree knows from an equal number that nothing in it changed since, save the subtree’s placement in its parent.
