 Overviewer at a High Level
 ==========================
 
-Minecraft worlds are rendered in an approximated Isometric projection at an
-oblique angle. In the original design, the projection acts as if your eye is
-infinitely far away looking down at the world at a 45 degree angle in the
-South-East direction (now, the world can be rendered at any of the 4 oblique
-directions).
