Scale NPC chat window with the rest of the UI

[Nubian]

The PS4 version might be running at 1280x720 or 1600x900. I'm not sure I don't have a PS4. I have seen people streaming the PS4 version to twitch, where it was clearly running at 1280x720, but this may have been do the television have a native resolution of 1280x720.

I think it's running at 1080p but there is an option in the settings to run it in 720p (I have not ticked this option).

I think the PS4 version defaults to having every HUD element scaled to 120% instead of 100%. Possibly larger fonts as default as well, can't quite remember.

The default was 140% but I changed it to 120% straight away.
