Can you do this in both OS_WIN and !OS_WIN paths?

[erikchen, 2015/06/01 23:48:53]

Yes. I will do so in a follow up CL. DeepCopyHandle() isn't defined on OS_WIN
yet, so I'll need to add that to base/memory first.

I removed an unnecessary cast to base::SharedMemoryHandle.

     image_shm->reset(new base::SharedMemory(shm_handle, true));
     if (!(*image_shm)->Map(desc.stride * desc.size.height)) {
