I think there's a set of functions, that start with mywindow_, that are used
most places in the code for handling window matrices.  You could look at
those.  That's just off the top of my head though.  You'd also have to
modify mouse events to rotate too, of course.

IIRC, each used layer in the file corresponds to a specific preview pane in

It's cool your still working on this.
