Change isOpaque() of ScrollPane [Draw2D]

Finaly,I upload sample codes to cvs.
see here
http://cvs.sourceforge.jp/cgi-bin/viewcvs.cgi/akjrcp/draw2dexample/src/example/draw2d/

I'm sorry,I don't have any way to know other platform results.
So I guess sometime on non-windows platrom it's didn't work correctly.

isOpaque methods of Scrollpane return always true.
but if you don't like it,overwrite it.

public class NoOpaqueScrollPane extends ScrollPane{
public boolean isOpaque(){
return false;
}
}
