+ * <li>1.0 (roi) :<br>
+ * <ul>
+ *  <li>Initial revision, October 5th 2009
+ * </ul> 
+ * </li>
+ * 
+ * <li>
+ * 1.1 (mui) :<br> 
+ * <ul>
+ *  <li>Changed displayFrame to DisplayFrame(naming convention) - Added new constructor for setting the window title.
+ *  <li>Changed visibility of background as an accessible member {@link #backgroundColor}.
+ *  <li>Made the clean function faster by using a clipping mask.
+ *  <li>Added {@link #setPixel(int, int, Color)} and {@link #setPixel(int, int, int)} methods. 
+ *  <li>Changed behaviour of the init function to display {@link #backgroundColor} as initial color.
+ *  <li>Added default constructor behaviour to enable changing window title.
+ *  <li>Added threaded pause function ({@link #pause(int)}).
+ * </ul>
+ * 
+ * <li>
+ * 1.2 (mui) :<br>
+ * <ul>
+ *  <li>Changed paint method for flicker-free and smoother behaviour (which also means that <code>repaint</code> calls have 
+ *  been replaced by <code>invalidate</code> calls). 
+ *  <li>Added rendering hints for nicer display.
+ * </ul>
+ * 
+ * <li>
+ * 1.21 (mui) :<br>
+ * <ul>
+ *  <li>Window is now centered on screen at startup.
+ *  <li>Window is now non-resizable.
+ * </ul>
+ * 
+ * <li>
+ * 1.3 (mui) :<br>
+ * <ul>
+ *  <li>Added key manager interface
+ *  <li>Changed members visibility
+ *  <li>Removed obsolete <code>display()</code> method
+ * </ul>
+ * 
+ * <li>1.4 (roi) :<br>
+ * <ul>
+ * 	<li>Added {@link fillOval()} method
+ * </ul>
+ * 
+ * <li>1.41 (mui) :<br>
+ * <ul>
+ *  <li>Changed how constructors handle rendering hints so
+ *  	that the quality can be chosen in the constructor instead
+ *  	of being hard-coded.  
+ *  <li>Added {@link #drawRotatedPicture(int, int, double, double, String)} method
+ * </ul>
+ *
+ * <li>1.42 (mui) :<br>
+ * <ul>
+ *  <li>Changed fields visibility and added getters/setters  
+ * </ul>
+ * 
+ * <li>2.0 (mui) :<br>
