Request: Tiled rendering mode

[LilyStilson]

What exactly do you want us to add?
Launcher will have ability to render it's threads as "tiles" in some 3D software. You start with a fixed amount of threads (some high number) and only few of them is able to render simultaneously. Something like Render Garden's rendering mode with Gardens and Seeds

Additional context
Actually, very possible to implement, since Launcher already can determine when specific thread finishes rendering. It just requires to clean up some code.
