When to draw?

[cheako]

#454 #180
Looks like the Redraw event is only sent rarely when the window should be Redrawn. When should draw calls be dispatched, for something like a clock showing ms or s or m?

The planned api changes I think explain when the event will be spawned: #1041 (comment)

Are you willing to implement it for MacOS, Wayland and/or iOS?

Especially in light of #1529, this should be good to close. Feel free to ask follow-up questions if need be!
