[Transformer] Overlay rotation around the X and Y axles

Thanks for you comments! Nice to see the work is appreciated.

Spinning around the x or y axis would be a 3D customization, and we don't support those in overlays sadly as we found combining different geometric operations didn't work as well as we'd hoped in would as the aspect ratio was often a little off.

In Media3 version 1.1.1 we supported defining your own transformation matrix. You could play around with that version and that api and see if you can get a lateral or vertical rotations working that by the gl matrices yourself and passing it in. We have a 3D spin effect that can show you what matrices are involved in creating a rotation around y axis. If the setMatrix() api proves useful then we may consider bringing it back in another form.
