From acd0d59e3c09f04bffd178aecd3638d3e189faba Mon Sep 17 00:00:00 2001 From: dsinclair Date: Thu, 21 Apr 2016 11:06:27 -0700 Subject: Cleanup FDE interfaces. This CL removes IFDE_TextOut, IFDE_Path, IFDE_RenderContext, IFDE_RenderDevice, and IFDE_VisualSetIterator in favour of the concrete classes.
