43 * The core is essentially a stack of layers. While running, it updates each
44 * layer from the bottom up every timestep. It also draws each layer from the
45 * bottom up, adhering to the maximum frame-rate. Events are sent to each layer
46 * from the top down until a layer signals the event was handled. The core is
47 * also responsible for firing timers on time. The core will continue running
48 * as long as there are layers on the stack.

91 * initialized. This is the mechanism to accomplish that. Classes which rely
92 * on any backend libraries just need to instantiate this class as a member.
93 * Backend cleanup will occur automagically when there are no more instances.
