+/* This snippet is used to display the circles indicating the number of windows open.
+ * Current window is indicated using filled in circle and others by an empty circle.
+ * In portrait mode, the snippet is placed below the status bar while in landscape
+ * mode, it is overlaid on the status bar
+ * Note: When overlaying the snippet there were some issues repainting when the background was set to none
+ * and hence a table with three cells are being used - the width of first and last cells match the
+ * area we need to see from the status bar and their backgrounds are set to none. The middle cell is
+ * used to display the circles and its bakground changes between black and white based 
+ * on the display mode.
