Is it possible to smooth coarse graphics?

I am using Graphics to draw vector objects and quality of render is quite low, every line roughly pixelated especially approximated circles. I have switched on s2d.defaultSmooth but it applies to texture smoothing. Is it possible to switch on antialiasing for vector graphics in heaps?

One way to do that is to generate a 2x sized Graphics, apply a filter to it, then scale it by 0.5, this will render it to 2x texture
