Class: WSIGenericViewport

Generic GenericViewport controller.

The base class owns only shared viewport state and binding orchestration: loaded logical data, mounted renderings, view state, and per-dataset render-state forwarding. It does not know how CPU, VTK, DOM, image, volume, or media runtimes work internally.

Concrete viewport families are expected to stay thin and provide:

• a render context for their render paths
• a data provider
• a render path resolver when the default is not enough
• viewport-family-specific public APIs

Concrete render paths are expected to own:

• runtime add/remove lifecycle
• view-state interpretation for that render path
• per-dataset render-state application
• render-path-specific coordinate transforms

This split keeps migration from legacy viewports incremental without centralizing render-mode-specific behavior in the controller.
