Inspired by jQuery.animate() properties can be interpolated using different easing functions and specifying an animation duration. Additionally animations can be chained to get table-based animations like with the current SGInterpolator, or also create looped animations or other more complicated curves. Currently this system is not used yet, but it is intended to replace SGInterpolator and allow more advanced animations of eg. also colors, for example, for the canvas.
