Zooms everything except for screenpack related items like lifebars, portraits, etc.
scale - The value by which to zoom in. A value of 1.0 or greater is required. A value of 2 will double the scale of all sprites.
pos - The position on screen to bind the zoom, relative to the center of the screen. A value of Pos X, Pos Y will zoom in on P1.
lag - Unknown; all it appears to do right now is break the SCTRL entirely.
type = Zoom
scale = value
pos = x, y
