From 660de3c494b68a574cb4cdf20359f51ddc260d3c Mon Sep 17 00:00:00 2001 From: npm Date: Mon, 8 Aug 2016 08:18:29 -0700 Subject: Move CFX_ClipRgn and CFX_PathData into their own files. This is the second CL in an attempt to split up the classes in fxge/include/fx_ge.h into their own files. CFX_ClipRgn is moved to core/fxge/ge because it is only used in core/fxge. The header for CFX_PathData is left in core/fxge/include since it is used elsewhere.
