TransformControls: If CTRL is kept pressed while rotating, rotate incrementally every 10 degrees?

[martinRenou]

Making use of https://threejs.org/docs/#examples/en/controls/TransformControls.rotationSnap we should be able to implement such thing

[martinRenou]

Noting that we should not only rotate incrementally but also force the rotation to be a multiple of that increment

[trungleduc]

The rotation should be in snapping mode by default, The increment value can be configured by a small input field in the viewport, under the Press R to switch mode text.

Sounds good!
