Careful, I do not think that will work - gl_draw() is *not* an OpenGL call, it’s a fltk method, with a "gl-like” name; in effect it is a substitute for fl_draw() that is intended to work in the GL context if a Fl_Gl_Window.
But it is not implemented as “pure” GL because it needs to interact with the fltk environment (e.g. for the text rendering, since the GL text rendering is... um... less capable... shall we say.)
So I doubt putting gl_draw() in a display list will ever work, frankly.
