*A short explanation of TOP and BOTTOM*
=======================================
A tile drawn with BOTTOM flag draws beneath the objects in layer order.
A tile drawn with TOP flag draws on top of the objects in layer order.

If you draw tiles on layer 1 and 2 with BOTTOM set on both, both will display in order 
beneath the object.

Tile 1->Tile 2->Objects

If you draw tiles on layer 1 and 2 with TOP set on both, both will display in order on top.

Objects->Tile 1->Tile 2

To draw normal tiles (Layer 1-> OBjects- >Layer 2), draw layer 1 with BOTTOM, and 
layer 2 with TOP

The top/bottom system yields the illusion of more than 2 layers.
