[smpeg] Difficulty porting SMPEG player's "update" from C to C++

Make this "static".

static void update( /* etc... */ );

>     SMPEG_setdisplay(mpeg, screen, NULL, update); // update called here
>                                                   // by referance

you might want to specify &MPEGPlayer::update.

You're trying to pass a class method to something that wants a straight C
function. Unless you specify that method to be "static", it'd expect you
to pass a "this" pointer to the function.

Being static means it can't touch any instance members of the class, though.
