1//! A minimal example showing the steps needed to get started with the plugin.
2//!
3//! Controls:
4//! - Pan: Left mouse button + drag
5//! - Orbit: Right mouse button + drag
6//! - Zoom: Mouse wheel
7//!
8//! This controller relies on picking to determine what point to orbit around and zoom towards:
9//! your motion will be relative to the point under the mouse cursor.
