How about SurfaceSequenceSurfaceEmbedding?

+    : public NON_EXPORTED_BASE(SurfaceEmbedding) {
+ public:
+  explicit SurfaceEmbeddingUsingSequence(const SurfaceInfo& info)
+      : SurfaceEmbedding(info) {}
+
+ private:
+  void DelegateReferenceImpl(CompositorFrameMetadata* metadata) override;
+  void AddReferenceImpl(SurfaceEmbeddingOwner*) override;

[kylechar, 2016/12/08 02:02:46]

SurfaceEmbeddingOwners* owner

+  void RemoveReferenceImpl() override;
+  virtual void RequireSequence(const SurfaceSequence&) = 0;

[kylechar, 2016/12/08 02:02:45]

You should have a virtual destructor for an abstract class.

+  virtual void SatisfySequence(const SurfaceSequence&) = 0;
+  SurfaceSequence seq_;
+};

Again, should this be copyable?
