CSD icons don't scale with the font size
Hello,
Steps to reproduce:
- Set the font size to 15 (with GNOME, probably with gnome-tweak).
- Open gtk4-demo or gtk3-demo
Result: The CSD minimize, maximize, close button don't scale.
Expected result: The CSD icons should scale as it is the case with a title bar in Compiz 0.8 using libmetacity for example.
Note: This is important because without the scale, CSD icons are less accessible/visible to low-vision people or elderly than simple title bar.
Best regards.
