<p>The parent class, FSFillStyle allows the type to be set. This should only be used for manipulating bitmap and gradient fill styles.</p> 

<p>The FSMorphSolidFill object is added to a FSDefineMorphShape so both the start colour and end colour should have a value specified for the alpha channel that defines how transparent the colour is.</p>
