After this change, fit_widget() enforces that a widget cannot ask for more space
than was offered to it. This also fixes a rounding issue in the flex layout
where its fit function would return too small numbers.
Thanks to this, lots of "XXX" comments in spec/ disappear.

In expand nodes "none" and "outside", the variable size_remains describes how
much space is available for the first/third widget. Everything else is used by
the second widget. Thus, fitting the second widget to anything involving
size_remains is wrong. Instead, this commit uses the correct value.
This also fixes a messed up argument order for horizontal align layouts.

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 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.
The old code transformed the top-left and bottom-right corner of the rectangle
to device space and calculated a rectangle based on these two points. However,
if you rotate a rectangle by 45°, these two points will be directly above each
other and thus the old code would calculate a width of 0.
Fix this by transforming all four corners of the rectangle into device space and
calculating a rectangle based on this.

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.

Previously, odd things could happen if a widget was getting fitted into a
negative width or, even worse, width being NaN (not a number)!
This can e.g. happen due to a margin layout which doesn't get enough space to
even draw the margin that it is supposed to add.
Fix this by enforcing a minimum value of 0 for the width and height that a
widget gets fitted into.

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.

If a drawable has an opaque background, we don't need pseudo transparency and
thus its content don't change when it is moved. However, when we need pseudo
transparency, then we have to redraw the drawable to apply the new background.
Previously we just always did the redraw. This commit adds a helper function
gears.color.create_opaque_pattern() that analyzes a cairo pattern for
transparency. We use this new function to only redraw-on-move when there is
actual pseudo transparency in effect. Otherwise, this redraw can be skipped.

Added set_expand function with options of "none" "outside" or "inside" modes.
The "inside" mode is the default and will result in the original behavior. The
main benefit is being able to actually center a widget in the available space
with options of how to draw the outside widgets (expand to take the space,
or not.) Further functionality can be had by ommiting one of the outside
widgets. Set default layout mode in the constructor.

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

Let's consider the following notification:
naughty.notify({ text = "foo", bg = "#88888888", timeout=1 })
naughty.notify({ text = "foo", bg = "#88888888", timeout=2 })
When the first notification disappears, the second one is moved and takes its
place. However, its content was not redrawn. This makes the pseudo-transparency
break and the wallpaper that is shown in the back of the notification doesn't
match the real wallpaper.
Fix this by redrawing drawables when they get moved.

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.

The current code relied on some widget to cause a redraw when the focus changes.
Obviously, this assumption is wrong.
Instead, the code now uses the proper "focus" and "unfocus" signals for setting
titlebar colors, but it also needs to set these colors when a new titlebar is
created (v1 of this patch forgot that). For this reason, update_colors has to be
saved for when a titlebar's colors are updated.

This commit makes it possible to add titlebars to a client. These titlebars are

This makes the imagebox widget refuse images which have a zero or negative width

If you managed to press mouse button 4 exactly between two entries in the
taglist, the taglist would jump by two tags instead of just one. This is because
the mouse event was forwarded to both taglist items.
This happened because the calculation in wibox' find_widgets() was wrong. If you
have a widget at (1, 1) with a size of 1x1, then (1, 1) is the only point that
this widget covers. However, the math also included the pixels (2, 1), (1, 2)
and (2, 2) in the widget's extents. This is obviously wrong.
