Is there a RemoveImage() call? where does that happen? Seems odd having one here
in aw/ layer and not the other.
ISTM the factory method needs wrapping with another method that lives in gpu::
namespace and does this for us.

Let's discuss this when sievers@ comes back.

   return result.PassAs<gpu::GpuMemoryBuffer>();
 }
 
 }  // namespace android_webview
