Mon Sep 30 16:14:25 CDT 2002
Another big one.
ChangeLog:
-- Fix LIST mode, broken by previous changes
-- Implement GetItemRect in terms of GetItemMeasurements
-- Improvements in debug traces
-- Many bug fixes, compelete implementation for GetItemMeasurements
-- Lots of code cleanups, simplifications
-- Documentation updates.
