From 5a423ef8708e61d43f1556ab09c2e09f496d700d Mon Sep 17 00:00:00 2001 From: Dan Sinclair Date: Tue, 14 Nov 2017 18:56:54 +0000 Subject: Rename the fxgraphics classes The build system doesn't like name clashes over directories in XFA. The Pattern and and Shading classes need to be renamed to not clash with future XFA node class names.
