Either do a windows spaning over both screens and set an
apropriate view****t with glView****t / glScissor, or create two
windows, each with it's own rendering context. Then you
can "select" the screen, by making the desired context current.
You can share objects (i.e. Display Lists, Textures, stuff like
that) between contexts, by supplying the context you want to
share with as the "shareLists" parameter of glXCreateContext.
