[ENHANCEMENT] Toggle Colorbox

[NullPlane]

Another potentially unique feature that came to my mind.
When hovering over color definitions, there is a preview.

Add a setting (pot. even w/ file type based behavior) to
automatically/permanently show these either in-line or
somehow, idk. Every color code permanently visible as clr.

could be cool for these css ppl etc. having preview boxes
that are permanently visible.

Not a priority feature I'd need but it sounded interesting
enough to bring it up here, could imagine some ux ppl'd
rly love it.

The small color-box alongside the color feature exists in a few editors, vscode activates this feature by default, it's certainly convenient but the main problem for ecode is that the renderer is not ready for these kind of extra inner elements within the code, they can only exist outside the code, implementing this feature would require to almost rewrite the whole renderer + selection logic (with a high performance penalty), that's why I also do not support inline hints (also because I really don't like them, I don't like the cursor jumping all over the place because there is text I cannot select or interact). The only viable alternative without rewriting everything is displaying these boxes without modifying the layout, there are a few options:

• Change the background color of the color text and adapt the text to be readable (this is doable, although, also requires some changes in the renderer, this is the best option IMO)
• Display the color box within the line number gutter (a single color could be represented per-line)
• Display a color box at the end of the line only if the line is not wrapped and fits inside of the view-port and there's a single color in it (this could be "good enough" for cases like colors in CSS files)

This is vscode:

what I thought is either

• A append "virtual" tab characters/boxes in-line that are colored
  (idk to what extend this is possible) similar to how it's done in terminals

OR

• B use the currently existing overlayed color frame and stretch it
  over the color definition. That'd hide #.../rgb(...) and interchange the
  relation (color is shown, hovering shows the color code). Adding a
  shortcut that shows this only while holding or with a timer is another
  possibility

maybe this timer or onhold approach could just be used with the current
approach to color rendering, showing all boxes.

Optionally, the color boxes, to not clutter code, could be, if toggled,
aligned to something like it's own #271 with a hint to where it comes from.

Yeah, A requires a big renderer+selector refactor, and B I really do not like it as an option, hiding code would be really bad IMO.
