Problem description:

I'm using Forum_Account's "Fog of War" library for a rogue-lite i'm playing around with. I can't seem to figure out how to make it respect the opacity of turfs (As is, I can see through walls) without byond's built in vision overriding the library, leaving everything out of view blacked out entirely (No "grey" fog showing turfs that have been seen before).

Has anyone found a way of doing this? Or, any ideas where I should start to go about this?
