I am looking for an editor, ide, tool or anything that lets me take a tile sheet (set of tiles) and easily, quickly build levels with them that I can export as a single PNG. I don't want or need to export the level as a tile map or special format, I just want to be able to create backgrounds basically.
Yes, Photoshop and Gimp do this, but I want a tool designed for it. With a little pallet of tiles I can just drag and drop.
Update: This seems to be pretty close.
