From 9eb0db1d7f6273de7eb28b0e1490eaf893e3bfb5 Mon Sep 17 00:00:00 2001 From: dsinclair Date: Thu, 21 Jul 2016 12:01:39 -0700 Subject: Move xfa_basic_imp to cxfa_widetextread. This Cl splits out the CXFA_WideTextRead class into it's own file. The helper methods have been moved into xfa_utils.cpp and their pre-declarations into xfa_utils.h.
