Prop: id
If you want to render multiple Goo components with different values for intensity and/or composite, a unique identifier should be supplied to every additional instance.
<Goo intensity="weak"> … </Goo>
<Goo id="second" intensity="strong"> … </Goo>
A different id is passed to the second instance.
<Goo intensity="strong"> … </Goo>
<Goo intensity="strong"> … </Goo>
<Goo> … </Goo>
<Goo> … </Goo>
In the two examples above, passing an id is not necessary since the underlying filter will be the same.
