addFeatureOverrideProvider Method
Add a FeatureOverrideProvider to customize the appearance of Viewport.Features within the viewport. The provider will be invoked whenever the overrides are determined to need updating. The overrides can be explicitly marked as needing a refresh by calling Viewport.setFeatureOverrideProviderChanged. This is typically called when the internal state of the provider changes such that the computed overrides must also change.
addFeatureOverrideProvider(provider: FeatureOverrideProvider): boolean

@returns true if the provider was registered, or false if the provider was already registered.
