gecko uses IDXGIResource::GetSharedHandle(). But it is recommend not to use anymore to retrieve the handle to a shared resource. IDXGIResource1::CreateSharedHandle() with D3D11_RESOURCE_MISC_SHARED_NTHANDLE flag should be used instead of the GetSharedHandle(). The CreateSharedHandle() could be called only once for a shared resource. Later calls fail. HANDLEs of ID3D11Texture2D are replaced by gfx::FileHandleWrappers.
