Dark mode menu

[AntonKhorev]

Dark mode filter menu from #4777 but without dark transport map tiles.

Unfortunately the context menu gets too large for small screens. Putting the options into the layer select sidebar may work better.

Will 100% brightness be the default? From what I understand to be the sole criticism (mine included) of the initial introduction dark mode was the dimmed map.

Seriously if we have to do this then we should just give up - it's not so much user friendly as user hostile to be giving space to something like this that is going to be completely incomprehensible to most users.

giving space to something like this

There was your suggestion to put the configuration into the preferences, and I kind of like it. Maybe a dropdown that allows you to choose how you'd like it to be. (There should be a map on the preference page then to preview the setting.)

No it wasn't. There are at least three different groups that complain:

• those who want the browser-reported preferred color scheme to be ignored
• those who don't want any tile filter, sometimes for performance reasons
• those who want their favorite tile filter

@mxdanger Sorry, I overrwrote your comment and there seems to be no undo in Github UI.

You said that there's an overwhelming feedback for not modifying the map and asked what should be the default.

But there is a feedback for doing inverse+hue-rotate transform.
