This allows to control which kind of icon actions can be done
on individual notifications. Once the second part of the permission
system will be merged, this will mostly be used in `ruled.notification`.
Currently, emit_signal always call all connected function. However,
it is very wasteful for some I/O intensive operations like icon
lookup. This commit adds a trick (private API) to stop once
a condition is met.
It will also in the future be used for the permission system, but
this is not yet implementd.
My initial implementation was overly optimistic. It turns out there
is no end in sight to "correctly" support icons. Apps randomly use
XDG name, paths and URLs. Rather than baloon the size of the
implementation, this commit moves toward to request:: pattern
found in other APIs. This will allow people who wish to "fix"
specific icons to do so in a way that scales.
The next 2 commits will move the current implementation to request
handlers.
Most of the notification code is from 2017. Soon after being written,
the permission system started to take shape. This required to
standardize the `request::` signals into the "object, context, args"
style. The notification code wasn't merged during that refactoring
and was accidently merged without the fixes.
Since this is still unreleased, I break the API now before it is too
late. Sorry about this.
Since it is used only one, use require() directly. This allows
to require it from `beautiful` without a circular dependency.
In turn, this allows to set colors using the rules rather than
adding an endless amount of theme variables.
This commit introduce the new "ruled" module. This new top level
module will eventually host all "rules" related modules.
As for the content of the commit, it adds rules for notification. They
are mostly identical to the client rules and can be used to customize
or filter the notifications. It replaces the old "preset" API. The
preset API inner working was mostly a duplication of the early
`awful.rules` API, but was never as flexible. Thus the idea behind this
work is to converge all "core" classes to use a similar declarative API.
When less space is available than was asked, systray:draw() has to
compute the right base size so that all the icons fit into the available
space. This computation so far ignored the icon spacing, resulting in a
too large base size.

The tag history kept a strong reference to a screen even after that
screen was removed. This prevented the garbage collector from cleaning
up.
Fix this by getting rid of the tag history on screen removal.
