initial "how do i size and lay this out" is a fuzzy algo that tries to
stuff all the windows into a single screen with several rows of
windows (in large mode). it has to trade off sizing for a squarish
layout with mu;ltiple rows so does some passes and tries and bisecting
etc. - the problem is each stage goes and does a lot of object changes
re-laying them out and querying them. this is expensive. this does a
row length calc on its own without the objects to save a whole lot of
overhead.
in theory i could actually skip almost all the object stuf and make
more assumptions and reduce the object fiddliong to just an initial
"how much fluff around a window item in the list and how much fluff
around the winlist (like padding/title and so on) and then just do
some raw math (and even flatten into arrays for cache friendliness).
but it's fast enough right now without a lot of changes. can always
revisit this in future.
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.

So yeah, I've literally used sed to replace every occurrence of
ecore_time_add() with ecore_timer_loop_add() because I'm reasonably
confident that no part of E has a legitimate need for timer based on the
exact current time.
It would be really nice if I'm not wrong. :)
The reason for this is the incredible spew of clock_gettime() calls I'm
seeing on an ARM system (that should have a vdso for gettime, but...)
This can amount to thousands of system calls per second.

now they can be trule async hopefully stopping things like application
menu from stalling while loading icons header... which is really nasty
with svg's. this actually makes icons async by default which is really
EXACTLY what you want. this also prepares for later making edje loads
async.

Summary:
The original next window selection of winlist is weak. It searches the next window with the following conditions:
1. Next non-overlaped window in the direction of user's selection (up,down,right,left).
2. The next window has to be the closest window from the currently selected window (calculated from shortest distance from each window's border, in the direction of selection)
3. the second distant requirement is this:
delta2_next = abs(ec_orig->x - ec_orig->w / 2 - ec->x + ec->w/2);
* Which I believe is a mistake, should be:
delta2_next = abs(ec_orig->x + ec_orig->w / 2 - ec->x + ec->w/2);
These two conditions are weak, and they sometimes can result in unexpected selection to the user.
The enclosed patch enhances the next window selection: 1) A next window selection can be the window that's overlapping with the in-focused window. 2) calculates the next window from the center of the currently focused window to the next window, and it also takes into account directionality (a window that's farther in the direction of selection has a better chance of being selected then a window that's closer in the direction of selection, but offset-ed in the lateral direction.)
Test Plan:
1. Create 4 key binds for "next window to left, right, up, down".
2. Open up 4 different windows and position them in odd/random positions.
3. Try to navigate to each window (with the winlist shortcut keys) before this patch.
4. Try with this patch, and evaluate if the window selection is more **PREDICTABLE**.

I fixed the weridness and it behaves much more reliably now with
"tall" or "wide" windows. also fixed some formatting etc. etc. - this
now works better and now if u alt+tab AND then use arrow keys while
holding alt... it'll navigate around geometrically rather nicely.
so big fixes and good for pointing out the simpleness of the original
code. :)

key handlers here will pick up both wayland and drm engine type events,
so ensure that we only handle events matching the compositor canvas
window to prevent unexpected behavior
fix T2637
if pointer warping is disabled, attempting to pointer warp with mouse-based
focus policies will fail here, preventing focus from being applied as expected
