Module backend 

Backend-facing API mirroring silx BackendBase.

This module defines the renderer boundary: high-level code passes item specs and view state through Backend, while concrete backends decide how to store and draw them. The specs intentionally borrow user data so callers can hand over slices; a backend that retains data clones them into its own item state.
