Previously, the Cogl backend was at times a subclass of the X11 backend, and at times a standalone one. Now it is the other way round, with GDK and X11 backends providing the concrete classes, layered on top of the generic Cogl backend. A new EglNative backend was introduced for direct to framebuffer rendering. This greatly simplifies the API design (at the expense of some casts needed) and reduces the amount of #ifdefs, without duplicating code. https://bugzilla.gnome.org/show_bug.cgi?id=657434
