-/**
- * Note: We are converting GrProcessor from ref counting to a single owner model using move
- * semantics. This class will be removed.
- *
- * This is used to track "refs" for two separate types GrProcessor ownership. A regular ref is owned
- * by any client that may continue to issue draws that use the GrProgramElement. A recorded op or
- * GrPipeline uses "pending executions" instead of refs. A pending execution is cleared after the
- * draw is executed (or aborted).
- *
- * While a GrProgramElement is ref'ed any resources it owns are also ref'ed. However, once it gets
- * into the state where it has pending executions AND no refs then it converts its ownership of
- * its GrGpuResources from refs to pending IOs. The pending IOs allow the cache to track when it is
- * safe to recycle a resource even though we still have buffered GrOps that read or write to the
- * the resource.
- *
- * To make this work the subclass GrProcessor implements addPendingIOs, removeRefs, and
- * pendingIOComplete. addPendingIOs adds pending reads/writes to GrGpuResources owned by the
- * processor as appropriate when the processor is recorded in a GrOpList. removeRefs is called when
- * the ref count reaches 0 and the GrProcessor is only owned by "pending executions".
- * pendingIOComplete occurs if the resource is still owned by a ref but all recorded draws have been
- * completed. Whenever pending executions and refs reach zero the processor is deleted.
- *
- * The GrProcessor may also implement notifyRefCntIsZero in order to change its ownership of child
- * processors from ref to pending execution when the processor is first owned exclusively in pending
- * execution mode.
