Add units support (POINT, PIXEL, SPACE) (#2578)
* add units support (POINT, PIXEL, SPACE) for polybar

- add a size_with_unit struct
- add a geometry_format_values struct
- move dpi initialisation from renderer.cpp to bar.cpp
- add a string to size_with_unit converter
- add point support (with pt)
- add pixel support (with px)

* Fix unit test compilation

* clang-format

* Better names

The old names didn't really capture the purpose of the structs and
function.

space_type -> spacing_type
space_size -> spacing_val

size_type -> extent_type
geometry -> extent_val

geometry_format_values -> percentage_with_offset

* Remove parse_size_with_unit

No longer needed. The convert<spacing_val> function in config.cpp
already does all the work for us and always setting the type to pixel
was wrong.

In addition, line-size should not be of type spacing_val but extent_val.

* Cleanup

I tried to address most of my comments on the old PR

* Fix renderer width calculation

We can't just blindly add the x difference to the width because for
example the width should increase if x < width and the increase keeps
x < width.

Similarly, we can't just add the offset to the width.

* Rename geom_format_to_pixels to percentage_with_offset_to_pixel

* Cleanup

* Apply suggested changes from Patrick on GitHub

* config: Use stod for parsing percentage

* Use stof instead of strtof

* units: Fix test edge cases

* Remove unnecessary clang-format toggle

* Use percentage_with_offset for margin-{top,bottom}

* Support negative extent values

* Rename unit to units and create a cpp file

* Move percentage_with_offset_to_pixel unit test to units

* Add unit tests for units_utils

* Clarify when and how negative spacing/extent is allowed

Negative spacing is never allowed and produces a config error.

Extents allow negative values in theory, but only a few use-cases accept
it.
Only the extent value used for the `%{O}` tag and the offset value in
percentage_with_offset can be negative. Everything else is capped below
at 0.

The final pixel value of percentage_with_offset also caps below at 0.

* Fix parsing errors not being caught in config

* Print a proper error message for uncaught exceptions

* Cleanup module::get_output

All changes preserve the existing semantics

* Stop using remove_trailing_space in module::get_output

Instead, we first check if the current tag is built, and only if it is,
the spacing is prepended.

* Remove unused imports

* Restore old behavior

If there are two tags and the second one isn't built (module::build
returns false), the space in between them is removed.
For example in the mpd module:

format-online = <toggle> <label-song> foo

If mpd is not running, the mpd module will return false when trying to
build the `<label-song>` tag. If we don't remove the space between
`<toggle>` and `<label-song>`, we end up with two spaces between
`<toggle>` and `foo`.

This change is to match the old behavior where at least one trailing
space character was removed from the builder.

* Add changelog entry

* Remove unused setting

* Use percentage with offset for tray-offset

patrick96 cd1d4fa183 Stop tracking action blocks in renderer
Dispatch can now directly get the current position from the renderer and
create action blocks with the proper coordinates.

patrick96 464bedb33c Store all action info in action_context
The renderer is responsible for setting the start and end positions
while dispatch does the rest

patrick96 96239597ed Move most action state out of renderer
The renderer now only stores the positions of the actions because that
is specific to the renderer and because the actual position can only be
finalized after all the rendering is done because intitially the
positions are relative to the alignment and not the bar.

patrick96 0a474bb2f2 Move trivial formatting state into tags::context
The variables storing the current colors, attribute activations and font
were only used in a single place and can easily also be read from the
context.

This allows us to remove a lot of the state of the renderer.
