-	Cool Scrollbar Library Version 1.2

-

-	Module: coolsblib.c

-	Copyright (c) J Brown 2001

-

-	This code is freeware, however, you may not publish

-	this code elsewhere or charge any money for it. This code

-	is supplied as-is. I make no guarantees about the suitability

-	of this code - use at your own risk.

-	

-	It would be nice if you credited me, in the event

-	that you use this code in a product.

-

-	VERSION HISTORY:

-

-	 V1.2: TreeView problem fixed by Diego Tartara

-		   Small problem in thumbsize calculation also fixed (thanks Diego!)

-

-	 V1.1: Added support for Right-left windows

-	       Changed calling convention of APIs to WINAPI (__stdcall)

-		   Completely standalone (no need for c-runtime)

-

-	 V1.0: Apr 2001: Initial Version
