Deja vu all over again.
Why not just generate the map as a 2D array to start off with
then just draw it isometrically? Saves a lot of bother.
Otherwise, pretend the first tile is at 0,0. As you generate new tiles
calculate their (x,y) position relative to the first tile.
Keep track of the smallest x, the smallest y, the largest x, and
the largest y. From there it's easy.
