Subject: lablgl and then feedback mechanism

I'm a new user of this list, and a new user of ocaml as well.

I would like to use the feedback mechanism of opengl which should send 
you the list of drawing orders performed by the opengl engine. This is 
interesting, for instance, for producing a postscript output.

does anyone know whether this is implemented in lablgl, and how to use it ?

I can see with ocamlbrowser that

GlMisc.render_mode `feedback;;

does exist. So I thought that was it ! Unfortunately I don't see the command

GlMisc.feedback_buffer ();;

(or something like this) which, according to the opengl doc, is 
necessary to define where the feedback orders are queued.
