Images should include dimension attributes. Without `width` and `height`
specified, image dimensions are 0×0 pixels at first. ... In this case the
browser determines that all of them are visible to the user and decides to load
everything [1].
In CSS the `width` is set to a value and the `height` is unsed to scale the image
proportional in both dimensions.

Add the 'SearXNG JavaScript Style Guide' as one quality gate in the build chain
of the simple theme::
make themes.simple
make themes.simple.test
In the github CI the `themes.all` target enforce a `themes.simple`.
BTW: Remove 'jshint' left overs from 0ee316f3d

All three filters (`language`, `time_range` and `safesearch`) are rendered in
one line. A size of 45% for `language` and `time_range` left only 10% for the
`safesearch` filter. Solution: drop with from `language` and `time_range`.

The CSP issue is, that the `_Position` function in the autocomplete-js set the
style attributes by `setAttribute("style", ...)`. Using `setAttribute` to set
the style attribute invokes the HTML parser and CSP is triggered [1].
This patch overwrite the `_Position` function of autocomplete-js.
BTW: remove trailing whitespace

Include the source files directly in the `.map` files [1] for two reasons:
1. In the simple theme, modules from `./node_modules` are only available on
developer's build host (a `make node.env` is needed to get the sources). By
example; in the `searxng.min.js.map` file, the `autocomplete.js` is linked at
URL:
../node_modules/autocomplete-js/dist/autocomplete.js
2. Later, when client sources has been moved out of the `./static` URL [2] to
the `<repo-roo>/src` folder, all JS sources are no longer available.
Drawback: `.map` files grow up in size, but this should not bother, because the
files are only loaded in debug mode.

remove:
* searx/static/themes/simple/js/searxng.head.js
* searx/static/themes/simple/js/searxng.js
* searx/static/themes/simple/css/searxng-rtl.css
* searx/static/themes/simple/css/searxng.css
These files are never used.
About the js files: the .map files references the sources instead of the concated version.
In window.searxng.theme the theme data can be passed through to JS
implementations.
Initial the window.searxng.theme namespace starts with a value for
`img_load_error`::
// image that is displayed if load of <img src='...'> failed
img_load_error: 'img/img_load_error.svg'
The searx/static/themes/__common__/js/image_layout.js is patched to uses the
value, if the theme defines a value for img_load_error in this namespace.

The *background color* of an transparent image is the color of the color of
wallpaper on which all images are shown on.
Set variable `--color-result-image-background` and `--color-base-background` to
the same value.

* move `searx/static/themes/simple/img/searxng.svg` to `src/brand/searxng.svg`
* README.rst can use it without a reference to a theme.
* the simple theme can create `searx/static/themes/simple/img/searxng.png` using
the svg2png task
