Aalib in a window on mac?


I’m interested in trying to use the aalib facilities of SDL to create
an ascii output of a video input…I’ve got a sequence grabber that
gives me the latest complete frame in RGB in a temporary offscreen
world…I’m just not sure how to go about telling aalib how to deal
with this…

I was imagining that this could be done by having aalib output to
another offscreen world, then copy that to an onscreen window…but
it seems that aalib only wants to write to text windows…

anyone familiar with this?
