Diagram of isometric tile.

   w = 2h
   |____|
   |  __|____
   | /\ |  |
   |/  \|  | h = w/2
    \  /   |
     \/____|_



We know the width and height of the isometric tiles and the width and 
height of the isometric map. The question is how do I derive the 
dimensions of the array on the right.
