Read absolute finger positions on touchpad

[realmayus]

Is it possible to read the absolute position of fingers within a touchpad's "coordinate space"?

I want to create something similar to Apple's Preview app's signature writing feature: when you sign, you do that within the entire rectangle of your touchpad, which is much easier than dragging the cursor like when you're using a mouse.

I think you have to somehow get the NSEvent of each touch, and from there the the allTouches array of NSTouches, and then use normalizedPosition on that.

Not something you can do with Winit, I'd suggest you create and manage a NSView yourself, and then attach it as a subview of the Winit view.
