This is a feature request from the chat. Right now, only deprecated
hacks allow this to be implemented. This is a valid use case and
must be supported for HiDPI use cases.
It is now handled by the `wibox.container.border`. The current
implementation had many unhandled corner case and is less
flexible than the new API.
Some might argue deprecating the background from a background
container is... strange. This is true. However, keeing all
use case within the same codebase would make it too large.
The `gears.shape` support is incompatible with the border
widgets (which are used to implement the background images).
The goal is to catch cases where the return value exists, but is
forgotten. There was a large enough number of them to turn this
into a real check. Initially, I just wanted to implement it to fix
the problems, then delete the code. But since this is so common, I
think it is worth the annoyance.
Now always call both check_widget and make_widget_from_value. This
should make it a lot less confusing when randomly trying to create
a widget as all ways to do it slowly converge toward an unified
one.
The way background are rendered changed to accomodate issues regarding
cliping and border. However this broke the documentation examples.
This commit fixes this in the least hacky way I found.
Fixes#2727
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.
Fixes#2640
Ref #1373
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.
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".

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".

* Move table functions out of awful.util into new gears.table
* travis: Use v9999 prefix for full requests
Make sure no newly deprecated functions are used
* Move all `awful.util.table.*` calls to `gears.table.*` calls
Move table test functions from awful/util_spec to new gears/table_spec
Change awful.util.subsets call to gears.math.subsets in awful/key.lua
It does not provide much value. The version number is already known to
ldoc globally in the "description" variable.

local functions and metatable based constructors are not
documented unless an explicit @function is added.
Also add missing return values and fix formatting.
