Instead of just having an "EGL" renderer, there is now a separate winsys for each platform. Currently they just directly copy the vtable for the EGL platform so it is still only possible to have one EGL platform compiled into Cogl. However the intention is that the winsys-specific code for each platform will be moved into override functions in the corresponding platform winsys. Reviewed-by: Robert Bragg <robert@linux.intel.com>
