It's nice to see something on screen right away when we start making a game, so let's make that happen.
In a 2D game, Encompass needs to know which order that things should draw in.
Encompass draws things back to front using integer layers. A negative value means farther in the back. A positive value means farther in the front. So an object on layer 10 will draw on top of an object on layer -10.
