Fields

resource_cache: &'a mut ResourceCache

Allow access to the texture cache for requesting tiles

composite_state: &'a mut CompositeState

Current configuration and setup for compositing all the picture cache tiles in renderer.

compare_cache: &'a mut FastHashMap<PrimitiveComparisonKey, PrimitiveCompareResult>
