/**
|
|
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).
