I believe offsetting is possible. Whether it will work exactly as you wish is hard to say.

 

The part I was having difficulty with is using the edge transparency of antialiased objects to adjust the distance in a way that reduces jagginess. It could be that when I take a fresh look at it, a solution will be clear. That sometimes happens.

 

I have a question, couldn't one use two surfaces to do that and then use linear interpolation based on alpha? Two surface distance are based on min non-alpha and max alpha. I could do a sample of that approach if asked, and explain it.

 

 

Actually, never mind, I realize that it would give inaccurate distance. The better approach is using subsampling, thresholding. Or multiple distancing, thresholding, and subsampling.
