Advanced top-down camera.

[skejeton]

It should be able to:

• Rotate around the center of the view.
• Zoom in and out, relative to the cursor, but not clip through the ground and not go too far away from the view.
• Move around the cursor relative to the scale.

This can be done if I have a special camera structure instead of manipulating the generic camera structure:

struct TopDownCamera {
  Vector2    pos;      ///< 1 unit = 1 tile
  float      zoom;     ///< can be clipped
  Vector3    rotation; ///< pitch, yaw, roll
};
