From fcd7a3968daa37ea2184e281645832703b9b541a Mon Sep 17 00:00:00 2001
From: jenglish <jenglish@flightlab.com>
Date: Sat, 9 Jun 2007 21:45:44 +0000
Subject: Ttk_Manager API overhaul:     + Ttk_Manager no longer responsible for
 managing slave records     + Ttk_Manager structure now opaque     + Ttk_Slave
 structure now private     + Pass Ttk_Manager * to Tk_GeomMgr hooks instead of
 Ttk_Slave * ttk::labelframe: Simplified -labelwidget management.
 ttk::noteboook 'insert' command didn't correctly maintain current tab.
 Changed documentation of ttk::panedwindow 'identify' command to match
 implementation.
