Apparently there is an undocumented Zoom SCTRL in 1.1b.
[State 0]
type = Zoom
scale = value
pos = x, yParameters:
- 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.
Not sure what other parameters there are. Postype does not appear to do anything, which makes sense since they're deprecating it. This post will be edited as more information is found.
HUGE thanks to Websta for finding this!
