Minor Description
Apply a user specified Decorator (such as a ShadeDecorator) to the currently focused component to make it more visible.
This would be useful when debugging focus traversal issues and possibly from an accessibility perspective.
By default the Decorator would be 'null' and therefore not added to the focused component.
It could be set through a static method on org.apache.pivot.wtk.Component (allowing it to be changed at run time), and/or via a system property (like org.apache.pivot.wtk.debugpaint) or startup argument.
I have already developed this to satisfy my own requirement for the static methods on Component, but can add the other code and submit if deemed useful.
