Hi there, I have a question about this prototype on Framer site:

On Line 36:
point = Utils.convertPointFromContext(event.touchCenter, zoom, true, false)

I know what's utils means, but I don't know and cannot find convertPointFromContext on framer docs.
Anyone can tell me what's this line means? Thanks!

This function is used to convert a point (x, y) from one context to another. In this case, when you pinch, the event returns the point relative to the zoom layer. Then, the "convertPointFromContext" function is used to get the point that's relative to the screen context, which is basically the absolute position on the screen.
