-/** Frontend class for resources
- *
- * Usage:
- *	Resource::create("icon:noaccount")->applyTo(accountsAction);
- *	Resource::create("web:http://asdf.com/image.png")->applyTo(imageLbl)->placeholder(Resource::create("icon:loading"));
- *
- * Memory management:
- *	Resource caches ResourcePtrs using weak pointers, so while a resource is still existing
- *	when a new resource is created the resources will be the same (including the same handler).
- *
- *	ResourceObservers keep a shared pointer to the resource, as does the Resource itself to it's
- *	placeholder (if present). This means a resource stays valid while it's still used ("applied to" etc.)
- *	by something. When nothing uses it anymore it gets deleted.
- *
- *	@note Always pass resource around using Resource::Ptr! Copy and move constructors are disabled for a reason.
