cd6bcd470bThe `InterpolationRenderer` was violating the open-closed principle, because every time we would want to add a new modifier, we would need to change its implementation. This commit changes that behaviour by creating a `Modifier` interface. The classes implementing that interface are using a chain of responsibility to pass the data to the next one. Using a chain of responsibility makes a lot of sense, since it's only possible to have one modifier at a time.
