/*
Die Implementierung des JXMultiThumbSlider wurde wahrscheinlich nicht abgeschlossen.
Es ist dokumentiert:
 * Thumbs have no default visual representation. 
Also keine Renderer!

 * To customize the look of the thumbs and the track behind the thumbs you must provide 
 * a ThumbRenderer and a TrackRenderer implementation. 
Für ThumbRenderer und TrackRenderer gibt es Interfaces
und zwei rudimentäre Implementierungen
- 1. in package org.jdesktop.swingx.color
	class GradientThumbRenderer extends JComponent implements ThumbRenderer
	class GradientTrackRenderer extends JComponent implements TrackRenderer
- 2. in package org.jdesktop.swingx.plaf.basic als inner class :
    private class BasicMultiThumbSliderUI$BasicThumbRenderer extends JComponent implements ThumbRenderer {
    private class BasicMultiThumbSliderUI$BasicTrackRenderer extends JComponent implements ThumbRenderer {

- Der Track ist eine linie
- Die Thumbs sind simple grüne Rauten (Polygon)

mit ThumbDataListener werden thumbs aus JXMultiThumbSlider mit JSlider sliders synchronisiert,
so dass man mit beiden rumspielen kann
