this adds a live exposé style set of windows in large mode and 2d
navigation, allows it to stay up so you can bind to a single key or
mouse button to bring up and keep thre unbtil dismissed etc. ... this
requires theme changes and for now these changes have only been added
to the flat theme branch in efl - they will become default in the
future, so dont use this and expect it to work unless you also try the
flat theme default from the flat branch in efl. see
https://phab.enlightenment.org/T6726 for details on that.
this is not complete. it has some TODO items at the top with XXX: but
.. it's good enough now to share.
