Apply 2D physics-like motion to Pixi objects using GSAP.
The Pixi GSAP Physics node moves a display object according to an initial angle/velocity or X/Y components, with optional forces like acceleration, gravity, and friction.

Usage
- Set a Target, choose a Mode, configure velocities and forces, then Start.
- Use Auto Start for automatic run when the target resolves.
