a bit of a pipe dream as it's either
1. really expensive as you basically have to render N times more pixels and
then down-scale (you can do this.. but putting a buffer canvas IN an image
object and place the image object in a parent buffer canvas and just have there
image object scale the buffer canvas down - i actually use this for
thumbnailing etc.)
2. you need to have insanely tricky/smart code to intelligently sub-pixel
render only "edges" of things etc.

all in all - it is possible already with brute-force by just double-parenting
a canvas.
buffer canvas -> image object -> output canvas

(where the image object scales your first buffer canvas any way you like).

as i said. this doesn't come cheap.
