public interface Filter
A Filter represents an operation that transforms an image, such as replacing some of its colors with others. A Filter can be applied to a Sprite or SpriteSheet to create a new Sprite or SpriteSheet, or it can be included in a set of Filters that is provided to a Sprite or SpriteSheet upon its creation, allowing that Sprite or that SpriteSheet's Sprites to be drawn to a Graphics context using that Filter.
