Interface to query and set values specific to a single VarSpriteGroupScope (action 2 scope).
Multiple of these interfaces are combined into a ResolverObject to allow access to different game entities from a SpriteGroup-chain (action 1-2-3 chain).

Get a few random bits.
Default implementation has no random bits.
