App with prototype <color-input>

[sidewayss]

See #158. I just now made up the name <color-input>. The idea is that it's an emulation and replacement for <input type="color">.

I have a working prototype, without <color-swatch> and adapted to my existing app, here: https://sidewayss.github.io/rAF/apps/color/

App docs are here: https://sidewayss.github.io/rAF/apps/#color (I have yet to update them for this change)
Source is here: https://github.com/sidewayss/rAF/tree/main/apps/color

Check out the colored rectangles at the far right of the Start: and End: fields, the 2nd and 3rd rows in the form. They are <button>s that wrap a swatchy <div>, and open a <dialog> that wraps:

• a <color-picker>
• a <select> of color spaces
• and OK / Cancel buttons. The buttons are because I went for the lowest common denominator. The app is designed to work on mobiles too. My code adjusts the width, not the height, of the dialog - there's no way around it. It lets the position default.

I'll be posting the app in the color.js repo Show & Tell as soon as it's ready for release, in the near future. I am posting this here because I want to draw attention to the proposal in #158, and because this repo is more "experimental" and I'm looking for feedback on this before I release the app.

Thanks!
