Re: add calculating methods to bind

[Tom Eugelink]

I came up with this:

startXProperty().bind( *snap(*heightProperty().multiply(0.2)) )


And then:

    private DoubleBinding snap(final ObservableNumberValue other, final 
Observable... dependencies) {
        return new DoubleBinding() {
            {
                super.bind(dependencies);
            }

            @Override
            public void dispose() {
                super.unbind(dependencies);
            }

            @Override
            protected double computeValue() {
                return NodeUtil.snap(other.doubleValue());
            }

            @Override
            public ObservableList<?> getDependencies() {
                return new ImmutableObservableList<Observable>(dependencies);
            }
        };
    }

But that always returns 0... I feel this should have worked.
