The _cogl_context_check_gl_version function is meant to be called once Cogl has a GL context so that it can check whether the context found is supported by Cogl. However, only the stub winsys was calling this and it was doing it before Cogl had a chance to retrieve the function pointer for glString so it would just crash. This patch combines the two functions into one so that _cogl_context_update_features returns a gboolean and a GError. Then it can just check the context itself. https://bugzilla.gnome.org/show_bug.cgi?id=654440 Reviewed-by: Robert Bragg <robert@linux.intel.com>
