* #GstD3D11Device wraps ID3D11Device and ID3D11DeviceContext for GPU resources
* to be able to be shared among various elements. Caller can get native
* Direct3D11 handles via getter method.
* Basically Direct3D11 API doesn't require dedicated thread like that of
* OpenGL context, and ID3D11Device APIs are supposed to be thread-safe.
* But concurrent call for ID3D11DeviceContext and DXGI API are not allowed.
* To protect such object, callers need to make use of gst_d3d11_device_lock()
* and gst_d3d11_device_unlock()
