This function checks if a given cairo context has an empty clip. It was
written with the assumption that cairo_clip_extents() produces the x, y,
width, height of the clip extents. However, that function actually
produces x1, y1, x2, y2, where (x1, y1) and (x2, y2) are the corners of
the rectangles.
Due to the way the function is written, it will return non-zero numbers
when there is a translation (cr:translate()). Thus, this function worked
basically never.
Fix this by checking if both points have the same X- or Y-coordinate.

With draw_empty=false, :fit() can return 0,0. Then, when :layout() is
called, it will compute negative widths and heights. This can then cause
lots of problems later on.
Avoid this by having :layout() return nothing instead of producing
negative sizes.

This way their name doesn't get mangle by the broken magic. It will also
eventually allow to `error()` in the template when the implicit
`@function` is used.
This commit also fixes a large number of issues found while
proof-reading everything.
ldoc has a magical `@classmod` module type which tries to detect
what is a method and what is a static function. It fails about as
often as it works. This commit makes everything explicit to remove
such issues.

- Fill slider bar with a linear pattern based on current value (if `bar_active_color` and `bar_color` are correctly provided)
- Add examples for the apidoc
It makes some code easier to write. It is mostly useful when the margins
are exposed through another widget. In that case it avoids having to
proxy 5 different property or re-invent the wheel there.
Previously, the border "support" was limited to shapes and would not
move the content by the offset of the border. Borders are now better
supported and thus renamed from `shape_border_width` to `border_width.
In the end, shrinking the widget by the border size is too common to
ignore. It should have been the default all along, just like the clip.
* Fixed input_passthrough property not being set
In the table of properties supplied to the `wibox` function, you couldn't set the `input_passthrough` property. You could only set it after the wibox was created like this: `my_shlick_wibox.input_passthrough = true`. This commit fixes that and now you can set it in both ways.
Commit ba75da7976 worked around a bug in LGI. However, it did so by
just dropping the code that set the foreground color. Instead, it should
have changed the code so that cr:set_source() is only called if the
background container has a foreground color configured instead of "just
always".

When $SOURCE_DIRECTORY is set, we are most likely currently running the
examples test, i.e. generating images. These images end up in the
documentation.
To make the images reproducable, i.e. independent from the current time,
this commit makes the textclock honor $SOURCE_DATE_EPOCH if
$SOURCE_DIRECTORY is set.

cairo_get_source() is not bound correctly, leading to use-after-free
bugs. Cairo catches this and crashes.
Work around this by preserving the current source in a different way.
Instead of using cairo_get_source() and later cairo_set_source(), this
commit wraps everything that changes the current source between
cairo_save() and cairo_restore(). Thus, cairo saves the current source
for us without us having to grab an explicit reference.

Previously, the background container "just" used the shape and drew a
line around it. This means that half the line will be inside of the
shape and half of it will be outside. Thus, this hides the actual shape
that is used.
This commit changes that so that the line is added outside of the shape.
It does this via some tricks:
- In :before_draw_children(), :push_group() is used to redirect drawing
of the child widget to a temporary surface.
- In :after_draw_children(), the border is added to this group.
+ For this, another temporary surface is created. It will be used as a
mask.
+ The inside of the shape on this mask is cleared, everything else is
filled. Thus, the mask now contains everything "not content".
+ Everything inside the mask is filled with the background color.
- Also in :after_draw_children(), the group is drawn to the actual
target surface.
+ Again, this needs a mask.
+ This time, we draw the shape to the mask with twice the border width.
Thus, half of this line will be outside of the shape.
+ Then, the shape itself is also filled so that the mask contains the
shape and the border.
+ This mask is then used to copy the right parts of the temporary
surface were the child widget and border was drawn to the actual
target surface that will be visible on screen.
This approach has some upsides. Because we no longer have "half the
border" above content, colors with some transparency work fine for the
border. Also, this should avoid issues with anti-aliasing, because e.g.
the border is not just drawn with the border width, but also further out
to everything else so that the background cannot "bleed through".

Before this commit, it was added by `wibox.widget.base` if
`:setup()` is used. However it doesn't work for the `awful.popup`
because of the extra indirection.
This commit stops the monkey-patching and make sure the function
always exists. This doesn't prevent it from not working and in
the long run this should still be moved into the hierarchy.
However for now it makes the situation a lot more consistent and is a
quick band-aid without too much controversy.
Mitigate #2181
It is not possible to distribute 100px to three widgets equally. The
current version of wibox.layout.flex tries to do that anyway, by giving
each widget 33px and leaving one pixel outside of any widget. Thus, if
the widgets e.g. have a common background, this leads to a one pixel gap
in the background.
This patch changes the flex layout so that the extra pixel is assigned
to some widget instead. It does so by basically keeping a sum of
space_per_item for the widgets that was assigned so far. This sum is
rounded and when this leads to rounding, the corresponding child widget
gets an extra pixel.
More precisely, this tracks a pos as before. Widgets get their position
still assigned based on rounding pos. However, this now also remembers
this rounded position for the next iteration of the loop. This allows to
assign the size of widgets based on the difference between the current
and last rounded position.

Do it now since the future awful.popup and notification widget
also uses it.
The `load_ldoc.cmake` changes allow to include `.ldoc` blocks in
existing ldoc comments. Previously, it added some extra newlines
and an autogenerated comments saying the content below was imported.
The problem is that this prevented the system to be used for shared
function arguments.
This commit also renames the `wibar` argument table from `arg` to
`args` as the name has to be the same in the `wibox` and `wibar`
constructor for this to work.
The ratio, fixed and flex layout can now display a widget between
each layout elements.
The align layout was left out because it doesn't support spacing
If g_date_time_format() fails, it returns a NULL pointer. This change
makes the textclock detect this and print a warning. This warning
contains 'g_date_time_format()' so that people can ask their favorite
search engine for the supported formats of this function. This warning
also contains the actual format string so that all the information is
available in one place and possible bug reports hopefully include the
format string.

Since beautiful.xresources.get_dpi(s) allows nil as argument to query
some "global DPI", the functions to query the size of a textbox also
allowed to use nil as the screen, even though this was never documented
to work. Commit a137655791 broke this by assuming a valid screen
object.
This commit makes a nil argument work again, but will cause a
deprecation warning in awesome 5.

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.

When doing w.shape_bounding = foo on a wibox, the code would first read
shape_bounding from the underlying drawin. This would create a
(possibly) huge cairo image surface that just waits to be collected by
the garbage collector, resulting in increased memory usage.
Fix this by checking the force_forward table first. This tables contains
the names of shape properties. Thus, the evaluation of this statement
gets short-circuited and the property is on the drawin is not read.

Most of the entries that are marked as "TODO: Get rid of these" were

This commit changes the systray widget, wibox.drawable and the C code to
fix the following bug: When the systray widget is removed from a
drawable without being moved somewhere else, the systray stayed visible.
This was because the systray is not drawn by awesome, but only placed.
When the widget is no longer "drawn", it stays wherever it was placed
last.
This change works by detecting the situation when the systray is
removed. Then, the C code is specifically told to remove the systray
window from the drawable.
Note that this is only a partial fix. This change works correctly when
the widget is removed completely, because it is no longer placed by its
parent widget. However, for example, when you do
wibox.widget.systray().visible = false, the effect is just that the
systray widget gets size 0x0. This is not really visible, but as far as
this change is concerned, the widget is still part of the drawable.

It should be called "align", but the name is already taken
It doesn't use awful.placement because it would break the dependency
graph.
Some cases previously required 2 wibox.layout.align layouts,
one for each axis. This is massively overkill to simply place
a widget at the center of a larger area.
This bridges between gears.shape and the shapes. So far, it does not try
to do any kind of anti-aliasing magic, so you get "steep edges".
