The OffscreenEffect class needs to expose a way for sub-classes to track the size of FBO it creates, in case it has to do some geometry deformations like the DeformEffect sub-classes. Let's move the private symbol we used internally in 1.6 to fix DeformEffect to the list of public symbols of OffscreenEffect. http://bugzilla.clutter-project.org/show_bug.cgi?id=2570
