Drop manually scaling UI elements
When using 'scale monitor framebuffer' actor sizes etc. are already in logical sizes so we don't have to scale anything.
Fixes #2412
This will cause the ui elements to be too small on
- X
- wayland without scale-monitor-framebuffer
Regarding X that won't be a problem in the future but I'm not sure we should already introduce regressions for X before OS 9? Regarding without scale monitor framebuffer I would argue we should treat not having scale monitor framebuffer as unsupported. Otherwise we would still have to keep all the code for a only rarely tested code path.
Depending on other opinions on already introducing regressions for X this is blocked until OS 9.
I think we should probably weight until OS 9 because we probably will have to drop the X session completely anyways. But at least for now let's not break it intentionally 😅
