Thank you.
I can’t see any obvious difference in speed either on a modern laptop.

NSView scrollRect has been deprecated, so replacing it is a good thing all 
other things being equal. Implementing true scrolling rather than redrawing 
would still be worth a try, as display doesn’t seem particularly fast.

I’ll apply it to my own branch and report back if users complain.
