InterpolationPoint (Geotools modules 32-SNAPSHOT API)

```
public interface InterpolationPoint
```
The InterpolationPoints have to be specified in ascending order of Data. They define a graph of points. LookupValues less than the Data value of the first InterpolationPoint are mapped to its corresponding Value. Accordingly, LookupValues greater than the Data value of the last InterpolationPoint are mapped to the Value of this one. LookupValues between two InterpolationPoints are interpolated between the corresponding Values.
Only numeric quantities are allowed for LookupValue and Data. Values are usually numeric as well. The interpolation of color-values requires the attribute mode="color" at the Interpolate element.s
