| The IInterpolator interface is implemented by classes that calculate |
| values for the Animation class. The Animation class |
| can handle parametric interpolation between Number values and |
| arrays of Number values, but it cannot handle different types |
| of interpolation, or interpolation between different types of |
| values. Implementors of this interface can provide arbitrary |
| interpolation capabilities so that Animations can be created between |
| arbitrary values. |
