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.

This way "that other widget" doesn't prevent the current widget from being
garbage collected.
Please note that this in all of these cases the widget under consideration does
have a strong reference to the callback function. This means that the callback
cannot be garbage collected until "this widget" itself is collected. Thanks to
this, this change is safe.

This made it easier to figure out where a file causing an error was
coming from, but I could imagine that this could become too noisy, and
that there is/should probably be a more streamlined way to enable more
verbose logging / error output.
When an imagebox was drawn with width or height zero, it tried to calculate the
needed scale factor for making the image fit. Sadly, this would be a division by
zero aka infinite in this case.
Fix this by just not drawing anything if there is no space available.

Given an imagebox i with i.resize_forbidden = false and a valid image set, the
call t:fit(0, 0) would return two times "not a number".
This is because the code first does some calculations to get the input image
into the available space and then tried to do some calculations needed for
scaling images up.
The first calculation already gave us h == 0 == w, the second calculation would
then calculate 0/0. This results in NaNs.
This was only noticed because NaN is not a valid table index in lua.
Fix this by returning 0,0 if we have an image of width or height 0 after the
first calculation. Since 0x0 images are valid in cairo, this also fixes the same
bug with such images.

This commit adds and uses wibox.layout.base.fit_widget(). This function is a
wrapper for widget:fit() that caches the result and thus speeds things up.
This is necessary because some layouts call :fit() from their :fit() and :draw()
functions. Nesting such layouts means that at the widget at the tail of the
stack gets its :fit() function called quite often. If this function is not
blazingly fast, this results in noticeable slowness.

This has to be removed because it breaks the fallback to the default config if
the first config already managed to create a systray widget. This doesn't mean
that it is suddenly possible to have the systray visible in more than one place,
it just means that awesome will no longer complain about this.

A hack around abusing the fact that width of a textbox is 0 when its
empty, while it's height is still set according to the font.

The systray widget's fit() function worked in the (rotated) user coordinate
space while the draw() function used device coordinates (unrotated). This meant
that width and height were swapped up in the calculations and the systray ended
up being way too small.
Fix this by making the draw() function use user coordinates, too. This means
that it needs some new magic to detect a rotated coordinate space. This, in
turn, means that the systray is now automatically rotated when you put it into a
rotate layout.
This might cause some minor breakage because people no longer need to call
:set_horizontal() on the widgets.
Thanks a lot to Alexander Gehrke for his help!

This patch gets rid of lots of errors that happen when beautiful.init() is not
called in the config. Most of them were missing default values.
Thanks to panthar for reporting this.

In 3.4, an imagebox' image is set via "box.image = foo". Since widgets are just
ordinary tables in 3.5, this will actually mess with the imagebox' image without
setting it correctly.
Fix this by renaming the entry to "_image".
A similar patch was applied to the textbox widget ages ago.

This saves space when constructing widgets, because some common cases can now be
done in a single line of code.
