Check out performance of animations

[ymyke]

Check out performance of animations: Esp. when running on battery power. -> Add some setting that helps speed up / slow down the animations. Then do some self-timing e.g. on burning a card that will automatically adjust that setting if necessary (i.e., animation takes too long or too short).

Is this an asciimatics issue? Or what is causing this? Is it the same in different environments (powershell, WSL, Linx, ...)?
