Anyways... here's another idea.

addtilemask("image.png");

What does it do? Lets you take an image the same size as a tileset(2048x512) and apply it as a definition mask to your tileset. Basically, you have a second image, the template, which you can define tile-types. White would be non-blocking, black would be blocking, blue water, green swamp and so on. This would let you lay out your tiles however you want. Of course there would be limits... I can't think of any way to do animation tiles, not like it matters they don't work in type 1 anyways. Stefan could define the colors on the wiki in the same layout as he's done for the level generator.
