Key-press overlay #79, PR #167 update tentative

[ludolpif]

WIP for asciinema/discussions#152, UI cherry-picked from daonb PR #167 without the event handling code into current develop branch.

Let me know if it's help doing it this way.

I'm unsure about the correct way to make the input events hooking, even with recents updates for #222 and despite my reading of #167 (comment)

Hey, I haven't looked at this since it's a draft and therefore I thought it's not ready to be looked at. There are some conflicts, but I'll take care of that, no wories. Given you haven't pushed more since opening this PR I figure it's in a ready-to-review state, right?

Hi, you're right. Thanks for pointing out that I leaved this PR out of my mind this summer. The project I may use this feature is delayed until a job switch but I hope work again on it in a reasonable delay.

If you have tips to clarify my mind about the following point :

It may help me going farther. I am a bit lost about the targeted architecture you imagine at a global scope.

Thanks for all the fish,
