Some of the virtual functions in CoglWinsysVtable only need to be implemented for specific backends or when a specific feature is advertised. This splits the vtable struct into two commented sections marking which are optional and which are required. Wherever an optional function is used there is now a g_return_if_fail to ensure there is an implementation.
