Controls how Diva loads static image bodies that do not use the IIIF Image API.
Remarks
required preserves Diva's canvas-safe CORS behavior. fallback retries a
failed anonymous-CORS static image once without CORS, while none uses that
non-CORS path immediately. Images loaded without CORS can be viewed but cannot
use Page View pixel filters or be saved from the filter view.
