From 134ac9105586407eb3b1e06001101ff893dd4a31 Mon Sep 17 00:00:00 2001 From: Tom Sepez Date: Fri, 15 Sep 2017 15:32:01 -0700 Subject: Introduce CPWL_Wnd::PrivateData class. First step in passing ownership of this memory to the CPWL_Wnd. In turn, nest two other classes that also require PrivateData to satisfy nesting rules. Move one stray #define to the appropriate file while at it.
