+
+#Base class is DrawingArea instead of Window to allow insertion.
+#new methods:
+#   update_image to keep the screenshot current.
+#   __subsample__ to scale the screenshot
+#   __draw_lines__ to highlight the selected area.
+#Calls to destroy have been removed, since this widget is meant to
+#live for an indefinite amount of time.
+#Click behavior has been changed. Selection now happens by left-click and dragging,
+#while right click resets the selection.

+#original file name is select.py in Istanbul-0.2.1
