`ExtensionRegistry::registerFactories()` doesn't do any work at runtime, its purpose is to guarantee that the linker won't strip away these factories as dead code because they're discovered at runtime as opposed to being referenced statically. So it's safe to call on engine creation because it's a no-op at runtime. Signed-off-by: JP Simard <jp@jpsim.com>
