/**
 * Access the native clipboard, windows only, write only.
 * Needs work to become fool-proof, you may look into WClipboard.
 * Since this class hacks a private method, it may be harmfull if
 * the underlying implementation is changed.
 *
 * Also, if you want to push more than one format into the
 * clipboard in the Jdk way, you have to do some work.
 * <pre>
 * Here is some pseudocode:
 *	public synchronized void setContents(Transferable contents, ClipboardOwner owner) {
 *		...
 *		Map formatMap = ...getFormatsForTransferable(contents, flavorMap);
 *		openClipboard(this);
 *		...
 *		for (format in formatMap.keySet()){
 *			DataFlavor flavor = (DataFlavor)formatMap.get(format);
 *			...
 *			myPublishClipboardData(format, ... translateTransferable(contents, flavor, format););
 *
 *		...
 *  closeClipboard();
 * </pre>
