+/**
+ * Res independent Graph + GraphUI integration demo
+ * using a GraphUI Shape and Graph text rendering
+ * within a regular GLEventListener, attached to a GLWindow.
+ * <p>
+ * This demo showcases how to integrate Graph and GraphUI with different projection variations.
+ * </p>
+ * <p>
+ * Pass '-projPersp' to main-function to use perspective projection, otherwise orthogonal projection is used.
+ * </p>
+ * <p>
+ * Pass '-projWin' to main-function to use orthogonal projection with window coordinates, otherwise [-0.5, 0.5] is being used
+ * </p>
+ * <p>
+ * Default projection is orthogonal with width = 1, world-model range [-0.5, 0.5].
+ * </p>
+ * <p>
+ * The world-model height is always scaled to window aspect ratio.
+ * </p>
+ * <p>
+ * 0/0 origin in its bottom-left corner, same as GraphUI
+ * </p>
+ * <p>
+ * Pass '-x <int>' and '-y <int>' widget position in window coordinates (bottom left origin). Default is center, i.e. half window width and height.<br/>
+ * Note: Reshape won't adjust and this is merely to demonstrate the coordinate space.
+ * </p>
