From 7ffb59f7f540a67fb808c1e5a2a7edfacf125e3a Mon Sep 17 00:00:00 2001 From: Dan Sinclair Date: Thu, 10 Aug 2017 10:16:06 -0400 Subject: Remove CFDE_Path This CL removes CFDE_Path. There is only one method, AddLine which is required, the rest can be removed. That method is moved to CFX_PathData which is what CFDE_Path is appending to anyway.
