Hey anyone got a code snippet to rotate a 
UIImage
in kotlin-wrapped iOS code? The compose imageviewer sample doesn't have this case covered, and trying to translate the common code online doesn't work. For example, this doesn't work: 
let rotationTransform = CGAffineTransform(rotationAngle: rotationAngle)
In Kotlin, I can do:
Copy code
val rotMat = CGAffineTransformMake(0.0, 1.0, -1.0, 0.0, 0.0, 0.0)
but now I need a way to apply it to my UIImage
@Dima Avdeev I see you wrote a lot of the code to do the image manipulation in imageviewer; do you have any tips? I'm just trying to do a simple image rotation

Sorry, I wrote it in past. And actually forgot some of this code. I think you can copy/paste it as is and try to shrink some redundant features.
