From 447b1f3ffc7e0df233d15300bbf8a85ce2bc7278 Mon Sep 17 00:00:00 2001 From: dsinclair Date: Thu, 8 Dec 2016 10:06:32 -0800 Subject: Move xfa/fwl/core to xfa/fwl. The core/ directory in FWL no-longer provides any context. This Cl moves all of the core/ files up to the fwl/ folder. As well, the CFWL_EvtFoo files are renamed CFWL_EventFoo and the CFWL_MsgFoo files are renamed CFWL_MessageFoo. The event and message preceed the type in order to keep the files sorted together and to make it clear that they're all related.
