I don't know.  It's certainly possible to do something more complex, but 
this is equivalent to changing the size with Options -> Set Default Font.

Again I don't know, but I don't think so.  AFAICS it's faster because 
redisplaying a single buffer without changing the window and frame size is 
faster than redisplaying all buffers in a frame and resizing the frame 
itself.
