  * This class allows the GrPipeline to communicate information about the pipeline to a
  * GrBatch which should be forwarded to the GrPrimitiveProcessor(s) created by the batch.
  * These are not properly part of the pipeline because they assume the specific inputs
  * that the batch provided when it created the pipeline. Identical pipelines may be
  * created by different batches with different input assumptions and therefore different
  * computed optimizations. It is the batch-specific optimizations that allow the pipelines
  * to be equal.
