From 9ada2d83cbb629f286936ebc7a208a61164f873b Mon Sep 17 00:00:00 2001 From: npm Date: Wed, 10 Aug 2016 07:51:38 -0700 Subject: Move CFX_RenderDevice, CFX_FxgeDevice, and CFX_GraphStateData into their own files. This is the third CL to separate fx_ge into classes, one per file. All fx_ge.h includes had to be replaced with new includes The method definitions for CFX_FxgeDevice were not moved to a single file. These methods are defined in two folders different from fxge/ge, so they were left untouched for now.
