/*TODO
 * Represents a sprite's current animation.
 *
 * An AnimationManager object contains a sequence of information describing a sprite's visual behavior
 * (animation spreadsheet frames, position, rotation, transparency, etc) throughout a corresponding sequence
 * of the game's update frames. This per-frame information is represented by the class
 * AnimationManager::AnimationFrame, and the sequence of this information by the AnimationManager::Animation
 * type.
 *
 * Also, an AnimationManager object contains a set of all the possible animations the sprite may need.
 * This set is represented by the AnimationSet class. Thus, a sprite needs but one AnimationManager object
 * to access any of the animations it requires, as long as these are all properly registered
 * in the AnimationSet object given to the AnimationManager object.
