Yes.  I believe the whole story is in the window(2) man page.
Anything you've been doing with memlayer
should be possible to translate into that interface,
which basically translates back into memlayer
calls after reaching the kernel.

Instead of using a transparent layer to overlap
the entire base image, you can create small opaque
windows and put them where you want, reordering
them as you find necessary.  Think about the
layering that rio has to do when moving windows
around.  All that is done with window(2).
