Edges are antialiased using the Direct2D per-primitive method of high-quality antialiasing.
Objects are aliased in most cases. Objects are antialiased only when they are drawn to a render target created by the CreateDxgiSurfaceRenderTarget method and Direct3D multisampling has been enabled on the backing DirectX Graphics Infrastructure (DXGI) surface.
