Blue Marble Layer
Displays NASA's Blue Marble next generation imagery at 500m resolution from an OGC Web Map Service (WMS). By default, BlueMarbleLayer is configured to retrieve imagery for May 2004 from the WMS at &https://worldwind25.arc.nasa.gov/wms.

Properties
Cache identity of this layer's tile source, or null when the layer isn't wired through a cache (network-only). Walks the layer's tile factory chain, looking for a CachedSourceInfoProvider — typically a CachedTileSource that wraps an IDB / gpkg / filesystem TileStore.
Functions
One-stop accessor for "this image layer's content view." Lookup order:
Download every tile within sector across the resolution range into the layer's underlying TileStore (when the layer was constructed with a CachedTileSource). Returns the launched Job for cancellation; returns null when the layer's tile factory isn't backed by a TileSourceFactoryAdapter (i.e. no source-based wiring, so bulk-via-source is impossible).
Specifies this Web Map Service (WMS) layer's configuration. The configuration must specify the following values: service address, WMS protocol version, layer names, coordinate reference system, sector and resolution. All other WMS configuration values may be unspecified, in which case a default value is used.
Toggle the cache-only flag on a cache-attached layer or coverage.
