In the particular case of pageScaleFactor I believe we already have 
eventSender.scalePageBy. (I think it's on eventSender rather than 
layoutTestController because it was first used to simulate Safari's 
pinch-to-zoom feature.)

Moving this feature to window.internals and adding other similar features seems 
fine to me.
