I guess requestor wanted to override the paint methods and wanted to paint the
track and thumb in own way for which he needs this values
public void paint(Graphics g, JComponent c) {
paintTrack(g, c, getTrackBounds());
Rectangle thumbBounds = getThumbBounds();
if (thumbBounds.intersects(g.getClipBounds())) {
paintThumb(g, c, thumbBounds);
}
}

It is mentioned in the spec to not modify the return value so maybe we are

I have pinged the requestor but have not got any response..I guess since these
methods aids in overriding the paint method, these should be sufficient..
