addResourceOrWarnIfNotLoaded()

void KisRequiredResourcesOperators::detail::addResourceOrWarnIfNotLoaded	(	KoResourceLoadResult	loadedResource,
		QList< KoResourceSP > *	resources,
		KisResourcesInterfaceSP	resourcesInterface )

Some resources, like filter configurations may be assigned to the layers without being loaded to the resource system. In such a case, the embedded resources will be loaded here, when we make a snapshot.
