/*
The purpose of LayerInterceptData is to provide a place to store data that is accessible inside the interception function.
It works by being a templated type with static variables. Every unique type used creates a new template instantiation, with its own
static variable storage. Thus interception functions that are templated correctly have per-template static data storage at their
disposal, which is used to query the next function in the chain and call down.
