UI that allows font size change for ALL windows?

[kryteneq]

Right, I've got my gaming PC rigged up to projector at 1920x1080 but the standard UI doesn't allow the font to be changed in most of the windows (for example in the Broker, Persona, Inventory and Quest Journal windows)

Chat windows are fine but I need to be able to change the size of the font for _everything_

So, is there a fairly simple UI that I can use that will allow me to change the overall font size to make it slightly larger?
