Draft: #9745: presets settings box icon scale
depends on !1195 (closed) !1198 (closed)
scales the tab icons on filter dialogs presets according to the custom icon size set by the user
This image also shows all the recent scale tweaks acting on GIMP.
The Left menu icon < and '+' is rather 'heavy' in my view, I'll try tweaking the .svg and see what happens.
