We're caching two things, either a node itself being rendered, or a parent storing a cached version of a child as rendered to an offscreen the size and location of the parent. If both the parent and child uses the cache this will cause a conflict in the cache as it is currently use keying of a node pointer which will have the same value for the node-as-itself and the child-node-of-the-parent. We fix this by adding another part to the key "pointer_is_child" which means we can have the same node pointer twice in the cache. Additionally, in the child-is-rendered-offscreen case the offscreen result actually depends on the position and size of the parent viewport, so we need to store the parent bounds in that case.
