Class Task

java.lang.Object

com.eduworks.ec.task.Task

public class Task
extends Object

Class with static methods to prevent unnecessary overhead with small operations that don't prevent drawing, but to setTimeout on methods that slow down the browser sufficiently to interfere with drawing. Uses a framerate timer to determine between the two.
