So, because of crbug.com/526196 , and after
https://codereview.chromium.org/1324413003 , this doesn't do anything anymore
actually (the GpuMemoryManager doesn't have clients to manage any more). Sohan
is kind of on the hook to remove those GpuMemoryManager bits as a follow-up but
it hasn't happened yet.
But bottom line, I think we can just remove this class (and
PassThroughImageTransportSurface::manager_ while we're at it).

+  }

+  ~AndroidImageTransportSurface() override {}

 scoped_refptr<gfx::GLSurface> ImageTransportSurface::CreateNativeSurface(
     GpuChannelManager* manager,
     GpuCommandBufferStub* stub,
     const gfx::GLSurfaceHandle& handle) {
   DCHECK(GpuSurfaceLookup::GetInstance());
   DCHECK_EQ(handle.transport_type, gfx::NATIVE_DIRECT);
   ANativeWindow* window =
       GpuSurfaceLookup::GetInstance()->AcquireNativeWidget(handle.handle);
   CHECK(window) << "Failed to retrieve window handle.";
   scoped_refptr<gfx::GLSurface> surface =
       new gfx::NativeViewGLSurfaceEGL(window);
   bool initialize_success = surface->Initialize();
   if (window)
     ANativeWindow_release(window);
   if (!initialize_success)
     return scoped_refptr<gfx::GLSurface>();
 
   return scoped_refptr<gfx::GLSurface>(
-      new PassThroughImageTransportSurface(manager, stub, surface.get()));
+      new AndroidImageTransportSurface(manager, stub, surface.get()));
 }
