Is there any way to implement two-finger pintch zoom in a custom renderer?

[mspark99]

I am using the qml examples: Scene graph: opengl/metal/d3d11 under qml.

I tried changing the texture coordinates for the renderer to implement two-finger pintch zoom, but this makes the mouse input coordinates incorrect. Fixing this requires remapping the input coordinates. I'm looking for an easier way to do this.

Is there any way to implement two-finger pintch zoom in Squircle Class(QuickItem)?
