Class ContinuousCollision

Swept AABB collision detection.

Usage:

const result = ContinuousCollision.sweep(
  { x: 10, y: 10, width: 4, height: 12 }, // moving box
  { x: 0, y: -600 * dt },                  // velocity this frame
  { x: 50, y: 0, width: 100, height: 10 }, // static obstacle
);
if (result.hit) {
  // Move only to t * velocity, then slide
}
