Hi Damien, I'll test the patch soon. Thanks for the awesome work.
What I meant about the controls was this: I love that you've included support for the rotate gesture, but rotating around the view plane isn't very useful. Alt+scrolling works for orbiting, but is a bit cumbersome compared to simpler gestures sans modifier. Since orbiting is a very common action I'd advise that it be mapped to the rotate gesture, replacing the view plane rotation. Though I wonder if all of this is customisable through the input editor? Or is it hard coded?
