Imports
java.lang.ref.SoftReference, java.util.ArrayList, .Iterator, .List, com.sun.scenario.effect.Filterable
A simple object pool used to recycle temporary images used by the various EffectPeer implementations. Image allocation can be a fairly expensive operation (in terms of footprint and performance), especially for the GPU backends, so image reuse is critical.
