Fix unexpected cropping with non 1:1 pixel aspect-ratio. The actual buffer width/height should be passed to gst_d3d11_window_render(), instead of the calculated resolution. The width/height values are parameters for copying d3d11 video memory. Also, aspect-ratio should be considered on resize callback to decide render rectangle size.
