mouseMagnify angle

I want to use mouseMagnify for a component with no fixed aspect ratio.

Is there a way to get the angle of the pinch gesture for mouseMagnify?

Our usecase is a waveform viewer, and I want to allow horizontal and vertical pinch gestures, but it seems it’s not possible with only one scalar…

EDIT: I found this related thread:

I’ll keep digging

EDIT 2: I’ll continue in Howard’s thread
