+    Adds a drop-shadow to a component.
+
+    This object creates and manages a set of components which sit around a
+    component, creating a gaussian shadow around it. The components will track
+    the position of the component and if it's brought to the front they'll also
+    follow this.
+
+    For desktop windows you don't need to use this class directly - just
+    set the Component::windowHasDropShadow flag when calling
+    Component::addToDesktop(), and the system will create one of these if it's
+    needed (which it obviously isn't on the Mac, for example).
