It's a shame all of these x.reset() dweets don't work on iOS... :(
u/rodrigo.siqueira

...thanks for letting me know about this iOS limitation. So, I’ll stop using x.reset and go back to using c.width instead.
u/0x61

Should be noted reset is working fine in iOS 18.1
u/magna

Dwitter could also monkey-patch 2d context to get x.reset() working
