- Remove lag when lots of walls are displayed on screen - If my computer with an ATI Radeon HD 4870 and 8 GM of RAM gets bad lag, it's gonna be terrible for lesser comps. When I display a 120x1024 room all at once with about 40% of the tiles walls, i get about 17 fps right now, when it's supposed to be 30 fps. However, I won't be doing screens that large in-game, so it shouldn't be as much of a problem.
- Try to fix some depth issues with multiple views. Right now if you display 2 copies of the room on screen at the same time with different resolutions, the depth on the smaller-res one will be messed up if the larger one reaches the edge of the room.
- Add "sticker" support. Stickers include anything like cracks, paintings, windows, etc, that are just graphics to decorate walls.

Final resolution will probably be 320x240 at double scale
