Rebase X11 fractional scaling patch

@3v1n0-guest Could you verify that the logic in this patch update is correct? This is the last thing needed before uploading mutter 45.1 to Ubuntu Noble.

It doesn't seem any logic change, right? Only the context here seems to change, is it?

merged

Ok, thanks. I think I was just tired in Riga when I was looking at this originally.
