[MNT]: Should set_size_inches be updated to use device_pixel_ratio? #21090
Description
Summary
set_size_inches currently uses
matplotlib/lib/matplotlib/figure.py
Line 2659 in eecdbbc
I haven't actually tried, but I wonder if that was missed in #19126, and should be changed to
canvas.device_pixel_ratio?
(Likewise, backend_macosx.py would likely need to be updated in the same manner?)
Proposed fix
No response
