TileUser Interface

Represents some object that makes use of Tiles in some way - e.g., by requesting and/or displaying their contents, querying their geometry, etc. Each Tile keeps track of its users via its TileUsageMarker. A tile with no users is eligible to be discarded view Tile.prune. Every Viewport is a tile user. It is occasionally useful to have a tile user that is not a viewport. Every TileUser is identified by an integer Id that is unique among all extant TileUsers. This Id must be obtained via TileUser.generateId. Every TileUser must be registered with IModelApp.tileAdmin before use via TileAdmin.registerUser and unregistered via TileAdmin.forgetUser after it ceases using tiles.
