There is a new internal Cogl function called _cogl_check_driver_valid which looks at the value of the GL_VERSION string to determine whether the driver is supported. Clutter now calls this after the stage is realized. If it fails then the stage is marked as unrealized and a warning is shown. _cogl_features_init now also checks the version number before getting the function pointers for glBlendFuncSeparate and glBlendEquationSeparate. It is not safe to just check for the presence of the functions because some drivers may define the function without fully implementing the spec. The GLES version of _cogl_check_driver_valid just always returns TRUE because there are no version requirements yet. Eventually the function could also check for mandatory extensions if there were any. http://bugzilla.openedhand.com/show_bug.cgi?id=1875 |
