I understand that the problem is generic, but Windows appears to have had it solved long ago. Why is that solution so elusive for Linux?

What is a "flip queue", (I can start guessing, but I'd like to see a non-guess.) and why can't it be done in X/mesa/drivers?
My guess says that you render off-screen, and put a pointer to that off-screen buffer into a "flip queue". Then during each blank interval they display the most recent entry and discard any stale entries. That then says that compositing might be a part of this.
Will Wayland/Weston correspond more directly to the "more advanced presentation layer"?
