It was set as `module` instead of `class` because ldoc was confused
set shown the methods as functions and functions as methods.
This commit set the explicit section so ldoc don't gress (wrongly)
This makes it possible to have the systray only visible on the primary screen,
which is the new default value. This also makes it possible to configure
directly on which screen the systray should be visible.
This breaks the API in the sense that people who use "the old method" to
configure the systray's screen possibly don't have a systray.

There's no point in having multiple instances of this, because there are no
per-instance settings and the systray can only be visible in a single place at a
time anyway.

* Better widget names when using the declarative syntax
* Add ratio.get_ratio to avoid using the private API
* Also support `set_widget` when swapping widgets
This commit makes these methods invoke the method on a widget in a protected
context. Thanks to this, e.g. the wibox and other widgets are protected from
errors in a child widget.
Additionally, fit_widget() now assumes 0 if a widget's :fit() method didn't
provide a number.

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.

This commit documents that a textbox already accepts a screen object where a
screen index is expected. Also, this changes the widget API in that a widget's
context.screen is now a screen object instead of a screen index.

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.
Instead of throwing a Lua error, the code now just prints an error message to
stderr on invalid markup. For callers which want to handle this case specially,
we add :set_markup_silently() which returns error messages.

Without this fix `wibox.widget.textbox` ignores current theme font
setting and resets it to the initial one.
It becomes handy when the initial theme is tweaked during runtime, ie.
in `rc.lua`. Other AwesomeWM components like `awful` (taglist,
tasklist, menu) are aware and do respect the actual theme settings.

This adds new functions to all widgets that allow to force a specific
width/height. These values override the result from :fit().

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.

This adds :get_preferred_size() and :get_preferred_size_at_dpi() which return
the size (=width, height) that the textbox would need if unlimited space is
available.
This also adds :get_height_for_width() and :get_height_for_width_at_dpi() which
return the height that the textbox would need if the given width is available.

If someone modifies a cairo surface and then sets the resulting object as the
image of an imagebox, the imagebox needs to redraw. Thus, since surfaces are
modifiable, we cannot assume that nothing changed when the same image is set
multiple times on an imagebox.
However, the dimensions of a surface cannot be changed and thus this does not
need to emit widget::layout_changed.

This commit does two things: It gets rid of the reference to the layoutbox that
the default config created and it changes the widget dependency cache to not
keep widgets alive unnecessarily.

This makes the textbox' :draw() and :fit() callbacks use the DPI that is
specified in the given drawing context. With this, the textbox now scales
correctly if different screens have different DPI values.

This has some positive results on the "benchmark test". Each single number is
the best one out of three runs.
Before:
create wibox: 0.0826502 sec/iter ( 13 iters, 1.157 sec for benchmark)
update textclock: 0.0186952 sec/iter ( 57 iters, 2.473 sec for benchmark)
relayout textclock: 0.0158112 sec/iter ( 64 iters, 1.028 sec for benchmark)
redraw textclock: 0.0015197 sec/iter (662 iters, 1.861 sec for benchmark)
After:
create wibox: 0.0825672 sec/iter ( 13 iters, 1.154 sec for benchmark)
update textclock: 0.00378412 sec/iter (277 iters, 4.216 sec for benchmark)
relayout textclock: 0.00259056 sec/iter (420 iters, 1.09 sec for benchmark)
redraw textclock: 0.00105128 sec/iter (958 iters, 1.79 sec for benchmark)
We see no significant change in the creation of wiboxes (99.9% compared to
before). Update (20% of the previous run time), relayout (16%) and redraw (69%)
are all sped up by this change.

Before this, dependencies between widgets where implicitly discovered by
recursive calls to base.fit_widget() and base.layout_widget(). However, it is
too easy to get this wrong (just call one of these functions from outside of a
widget's :fit() / :layout() function) and the resulting mess would be hard to
debug.
Thus, this commit changes the API so that callers have to identify themselves
and we can explicitly record the dependency between the widgets involved.
This also fixes a bug where no dependencies were tracked for widgets after
:set_visible(false). Whoops...
Sorry for breaking the API for adding this.

These caches, well, cache the result of the :layout and :fit callbacks on
widgets.
Clearing caches is done by recording dependencies between a widget. When a call
to base.fit_widget() or base.layout_widget() recursively causes another call to
such a function, this means that the earlier widget depends on the later widget.
This dependency is recorded and when the later widget emits
widget::layout_changed, the caches of all the widgets involved are cleared.

This table contains the drawable, wibox and titlebar that we are drawing on, but
also includes the screen and the DPI of that screen. This allows widgets to
depend on the DPI in their rendering.

Having two modules named "base" is confusing and "wibox.layout" doesn't contain
much useful stuff. This is a first step for removing wibox.layout by moving a
function which should only ever be used internally in awesome.
