For example, Xephyr reports its output with a size of 0x0. Since a
division by zero is in no one's interest, just ignore such outputs when
trying to compute the DPI value.
Thanks to @timroes for pointing this out:

This commit makes awesome automatically compute the DPI of a screen
based on its RandR outputs. If multiple outputs exist, the lowest DPI is
used.

Once upon a time, beautiful.xresources.get_dpi was added to query
Xft.dpi. That made sense since this queried an xresources property. Over
time, other, non-xresources-based ways to query DPI were added to this
function. Now, it makes no more sense to have this function here.
Also, recently it became possible to add new properties to C objects
from Lua code. Thus, we no longer need to have a get_dpi() function
somewhere, but can add s.dpi directly.
Thus, this commit adds s.dpi and makes everything use it. No functional
changes are intended.

This was broken in 9cb60b8 in PR #1597 (from myself).
focus() is not defined on the screen instance as method
but on the screen module as function.

Fix#1644
This extracts the code for finding the next screen
from focus_bydirection to a separate method on
the screen object.
The main reason was to use the finding code without
actually changing the screen focus but this should
incidentally make the code slightly easier to test
as well since both concerns can be tested in
isolation.

It does not provide much value. The version number is already known to
ldoc globally in the "description" variable.

Instead of using a weak table to save the last mouse position, this is
now saved directly as a property under the screen.

This adds a tparam alias "@screen" for "@tparam screen" (when used to
document e.g. arguments for callbacks), and "@screen_or_idx" when a
function accepts a "screen" or "number".
A client is supposed to go to a screen when:
* It has been started using `awful.spawn` with explicit instructions [1]
* An `awful.rules` rule **or any of its callbacks** set the screen [2]
* When something handle `request::screen` and/or `request::tag` in some
custom ways. [3]
* Some clients can request a screen and mean it (like MythTV/Kodi/XBMC and
some multi-window DAW) [4]
A client is supposed to go to the focused screen when none of the above are
true [5].
Other constraints:
* The screen need to be set only once, anything will will emit
`property::screen` many time and cause side effects.
* There has to be a single entry point to the algorithm, no multiple
"manage" handler.
* Awesome internals must use the `request::` signal API and not force
their decision outside of request handlers.
* Restarting Awesome must not change the client screen
Commit 2178744 fix use case number [1] and [2]. It actually fix [4] too, but
it is an accident and I am not sure we care about [4] anyway. Use case [1]
and [2], however, are very important.
Fix#1091
This reverts commit facf676b13.
Using capi.client.focus.screen to decide which screen is focused breaks
a multiscreen setup. At least makes it extremely annoying to use.
In particular, if you have a focused client on screen 1, move the mouse
to screen 2 and launch a new client, the new client appears in screen 1,
since screen.focused reports that current focused screen is 1, not 2
because of the focused client.
Close#1035Fix#1029
The requirement to call add_signal() was added to catch typos. However, this
requirement became increasingly annoying with property::<name> signals and e.g.
gears.object allowing arbitrary properties to be changed.
All of this ended up in a single commit because tests/examples fails if I first
let add_signal() emit a deprecation warning.

The problem was that get_square_distance() made the screen one pixel larger to
the bottom/right than it really was. Thus, the (x+0,y+0)-pixel of a screen that
was below or to the right of some other screen had distance zero to both of
these screens.
This commit fixes the screen size computation and adds a small unit test for
getbycoord() and get_square_distance().

When there are no screens, screen[1] causes an error. Thus, this isn't a safe
fallback for these functions. Instead, this commit makes the code prefer the
primary screen, if possible. If no screen exists, then screen.primary will be
nil, but at least it won't throw an error like screen[1] does.
(This also changes the outdated copy of getbycoord that exists in
wibox.drawable)

gears modules usually don't depend on Awesome C-API. This code has
been placed there for unclear reasons.
Also, there is ongoing work to unify each "concepts" API into one
single page. Having `gears.screen` go against this effort.
Because all our Lua code can now work with screen objects, most of the uses of
s.index that the previous patches added for reaching this goal can be removed
again.

We recently changed the C function screen_getbycoord() and this commit makes
awful.screen.getbycoord() use the same algorithm.
