I just spent too much time tracking down a bug that happened while drawing a
widget. This is the reason why we should apply sanity checks while widgets are
constructed, so that we get a useful backtrace.

This makes the code use the existing functions for setting widgets. That way,
all the sanity checks that the existing functions have are applied for this code
as well.
I just spent half an hour tracking down a bug where a boolean ended up as a
"widget" in a fixed layout. The symptom was that while drawing the widget, an
error happened. Via this change, the error would instead be flagged while
constructing the widget.

Since commit b2aaefd095, we correctly handle window gravities when
the border width of a client changes. Since most windows out there have a
NorthWest gravity, this means that most windows do not have this problem.
However, e.g. mplayer uses gravity "Static" and this causes this issue (any
gravity other than NorthWest will do).
This affects the fullscreen handling in awful.ewmh. The code has to set the
border width before it changes a client's geometry so that the move when the
border width changes doesn't matter.
No new integration test for this since I didn't find anything usable with a
non-NorthWest gravity. A test would be easy to write, just test if `c.fullscreen
= true ; c.fullscreen = false` restores the previous window geometry.

This module is partly broken since 2009 (the way to use it that is mentioned in
the docs doesn't actually work) because the mousefinder object doesn't have a
find()-method (the line doing "self.find = find" should do "self.finder =
finder.find"). Since no one really noticed, this module is apparently not used
much.
When someone wants to still use this, they are free to copy this to their own
config. It's not much code, but it's enough code that I am annoyed that we ship
something broken to users. Everyone who copies it to their own config will make
sure it works the way they want.

This layout allow each widgets to take 'r' percent of the total
space, where 'r' is configurable.
It re-implement the 'wfact' system used by `awful.layout.suit.tile`
This layout display the widgets on top of each other. It can also optionally
display only the first one.
The most common use case is to create a composited widget. Other use case
include the creation of a "paged" stack to only display the most
relevant widget without adding extra complexity to the parent layout.
This new syntax is inspired by the Awesome widget 3.2-3.4 API. It
allow cleaner widgets declaration. The produced code is usually much
shorted and easier to read than wibox.widget imperative syntax.
There is already a hack into `awful.widget.common`. This system aim
to make the hack obselete while preserving the useful part.
I think this is also necessary to properly support SVG (with DPI
and resize).
Finally, Qt handle this using the QBrush concept, where you can have
programmatic patterns. Cairo doesn't have this concept, so there is no
"clean" way to have programmatic brushes.
It's unused since commit 0aa4304bda. Before this was a stable sorting
algorithm since table.sort is allowed to be unstable. Apparently we don't need a
stable sorting algorithm anymore.

Any awful.titlebar.widget.button widget (e.g. floatingbutton or closebutton)
decides on the currently visible symbol based on several factors. One of them is
"is the client currently focused?" and thus the button has to be updated when
the client is focused/unfocused.
The way the code did this was to use client.connect_signal("focus", f) and
client.connect_signal("unfocus", f). However, these signals are never
disconnected and kept alive forever. The callback function had a strong
reference to the client (as an upvalue) and thus this also prevented the client
from being garbage collected.
Fix this by using c:connect_signal("focus/unfocis", f) instead. These kind of
signals are only kept alive by the client object and don't prevent it from being
garbage collected.
This fixes the new test that the previous commit added.

Until now, this layout was "append only". There was no official
APIs to remove, replace, insert and swap widgets. This is fine
for the usual wibox + sensors widget used by the majority of
users, but lack flexibility necessary to use the layout system
to place dynamic elements such as clients.
The methods introduced by this commit are also recursive. This
allow widgets to be decorated, wrapped and splitted without
having to add boilerplate code everywhere.
This remove duplicated code and will allow more "collection"
style layouts to be implemented without logic duplication.
This commit also do some small cleanup to remove duplicated
code now present in `awful.util`.

Go around a limitation of the lua language spec. The return value
of this method guaranteed `ipairs()` correctness.
Please note that both the official Lua and Luajit implementation
provide a sparse table compatible `ipairs()` and __len implementation
by default.
It is an internal API and is used by `gears.shape`, `gears.pattern`
and `gears.composition` only.
This commit also add `:rotate_at` and `:copy` methods.
It is necessary to have it beforehand when creating layout objects
for unselected layouts.
In the current layout system, there is no layout object, but to allow
tabs and dynamic tagging features like ion3, layouts cannot be stateless.
Before, it was the caller job to make sure the client wasn't floating.
This limitation is unecessary. awful.client.idx now return nil instead
of an error. awful.rules setting the master width factor are now
foolproof.
This code is imported from Elv13 config and make it very easy
to create shaped objects.
If accepted upstream, other shapes, such as arrow and powerline
will also be added. This commit introsuce the 2 most common
shapes, rounded rectangle and rounded bar.
This allow the most basic kind of stateful layouts to be created.
It is now possible to have layout instances instead of global
stateless layout arrange functions.
This allow layout "arrange" to be called less often and react on
the cause of the change itself rather than it's consequences
(usually, the "focus" signal).
Previously, the layout were re-arranged everytime the focus changed.
Now, with "raised" and "lowered", it require less "arrange".
"swapped" allow smarted layouts. Currently, swapped cause a full
re-arrange. It re-read the "index" list from scratch and create
a "new" layout. With "swapped", incremental layout changes are
possible.

Lua will remove objects as values from a weak table before these objects are
finalized, but as values only in the next garbage collection cycle after the
object was finalized. Up to now, gears.object uses a table with weak keys so
that :disconnect_signal() works. This means that a signal can still call methods
which were already considered garbage by the garbage collector and thus can use
userdata from the C side which was already finalized. Crashes and other bugs
result.
This commit changes the code so that the function is also a value in the weak
table. Thus, the GC will remove the entry before the object is finalized.
Special magic is needed for Lua 5.1, because there only userdata has the
behavior that we want while we have a function. We do some magic with function
environments to make this work...

When emitting layout_changed, the widget is relayouted. If this doesn't actually
change anything, nothing will be redrawn. Thus, this also emits redraw_needed to
force redraws.
This fixes a race condition with some weird tray icons. A new tray icon is
created and the systray is updated. Then this new icon is destroyed immediately
again and at the same time another icon is created. Then, the systray isn't
updated since the number of icons (=the layout) did not actually change.
However, it needs to be updated and so we ended up with broken/missing icons.

Usually users want a wallpaper on all their screens. With the current code, this
resulted in a loop of upload-wallpaper, {download-wallpaper, add-new-part,
upload-wallpaper}*.
Fix this by being more intelligent: Instead of setting the wallpaper
immediately, this now uses gears.timer.delayed_call() to set the wallpaper. All
following modifications which come in before the delayed call runs will still be
part of the current update. This should mean that during startup, there is just
a single upload of a wallpaper.
(The above is what happens if there is no wallpaper yet. If there is already
one, we use :create_similar() and thus should only upload the part of the
wallpaper that changed, but this doesn't really make a difference.)
As a side-effect, the new code no longer draws to the old wallpaper to modify
it, but always creates a copy of it. This means that:
