--- Comment #3 from Esme Povirk madewokherd@gmail.com --- Apparently my Windows 10 VM has updated Pen Width reporting behavior (Width set to <1 is reported as 1), but not the new rendering behavior. So I can't use that to check.
The VM is 21H1, and I have gdiplus.dll version 10.0.19041.1348. The gdiplus tests pass in my VM as-is.
