+ [GTK] [EFL] Collapse duplicate WebGL support code
+ https://bugs.webkit.org/show_bug.cgi?id=78970
+
+ Reviewed by Gustavo Noronha Silva.
+
+ No new tests. This just cleans up duplicated code.
+
+ Centralize duplicated WebGL code for EFL and GTK+ in the Cairo
+ directory. This is in preparation for the changes necessary to
+ connect WebGL to the TextureMapper AC.
+
+ * GNUmakefile.list.am: Update source list.
+ * PlatformEfl.cmake: Update source list.
+ * platform/graphics/cairo/DrawingBufferCairo.cpp: Renamed from Source/WebCore/platform/graphics/gtk/DrawingBufferGtk.cpp.
+ * platform/graphics/cairo/GraphicsContext3DCairo.cpp: Integrated the code From GraphicsContext3DGtk.cpp.
+ * platform/graphics/efl/DrawingBufferEfl.cpp: Removed.
+ * platform/graphics/efl/GraphicsContext3DEfl.cpp: Removed.
+ * platform/graphics/gtk/GraphicsContext3DGtk.cpp: Removed.
