Working on the automapper

I've been spending a lot of time getting the automapper in tip-top shape for my big content push -- trying to iron out bugs in when rules match (which is how it decides what image to place per tile based on what's around it) as well as adding some functionality around decorative tiles (like the girders or struts supporting that platform) and getting layers working.

Most of the tiles in the screenshot are in the background and the player passes over them, but the decorative girders/struts column is in the foreground layer, and the player walks behind. Small change but it leads to big possibilities!

Next up is switching out the kind-of undifferentiated paneling in the background, which is generated randomly, with something more rule-driven as well. I also want to drive up the contrast between the tiles and player and the paneling background, graphically.
