From 893822aa5b6254591f8e80fbffcbb4fa6ad849aa Mon Sep 17 00:00:00 2001 From: Dan Sinclair Date: Mon, 13 Mar 2017 15:32:07 -0400 Subject: Merge text breaking helper classes. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This Cl merges the CFX_TxtPiece and CFX_RTFPiece classes into CFX_BreakPiece. CFX_TxtLine and CFX_RTFLine into CFX_BreakLine and CFX_TxtChar and CFX_RTFChar into CFX_Char.
