+    WDL - Skinned/Resizing thumb scrollbar library
+    Based on the "Cool Scrollbar Library v1.2" by James Brown - http://www.catch22.net
+
+    Original version Copyright(c) 2001 J Brown
+    Modifications copyright (C) 2006 and later Cockos Incorporated
+
+    Note: for a more featureful, less hacked up version, you may wish to download the
+    original from catch22.net. It has lots of added features, whereas this version is
+    very much tailored for Cockos' needs.
