help shader dxdrawcircle antialias

hey guys, I wanna help on shader Im trying to put antialias with borderWidth

There is more spam than topic left. I didn't mind to help you, but it seems like you think that your time is much more important than everybody else.

So you give me no other option than to lock the topic... which is really a shame.
