+/**
+ * A non-native size grip which looks (and almost feels) like the native Win32 size grip.
+ * <p>
+ * The SHADOW_IN style causes highlight lines to be drawn at the right and bottom border.
+ * This style should be used when placing the size grip on top of the bottom right corner
+ * of a FramedComposite with style SHADOW_IN. If the FLAT style is set, the size grip is
+ * drawn in a Windows XP style instead of the normal Windows Classic style.

+ * <dt><b>Styles:</b></dt>
+ * <dd>SHADOW_IN, FLAT</dd>
+ * <dt><b>Events:</b></dt>
+ * <dd>(none)</dd>
+ * </dl>
+ * </p><p>
+ * NOTE: The visibility of this widget is controlled by the "maximized" state of the
+ * shell. The size grip is hidden when the shell is maximized, even if it has been made
+ * visible by calling <code>setVisible(true)</code>. getVisible() always returns
+ * the value set with setVisible(). isVisible() returns the true visibility, as usual.
+ * </p>
+ *
+ * <p>New in 1.6: Smoother resizing for a more native look &amp; feel. The window size is
+ * not updated more than once every 25ms to reduce the number of unnecessary repaints.</p>
+ *
+ * <p>New in 1.8: You can specify a parent Composite other than the shell which will be
+ * resized by the SizeGrip.</p>
