When I use setDisplaySize in matter, the image is the correct size, but the hitbox is way too big, how can I fix this?

an acceptable solution would be to fill the whole hitbox area with a color, but that is not ideal.

this will work

```javascript
//before changing the hitbox, only add functions that will change the image of the object, but not the hitbox
this.sprite = this.matter.add.sprite(100, 100, ' ').setDisplaySize(width, height).setTintFill(0x00ff00); 
// in matter, setDisplaySize will make the hitbox much bigger than needed but the image will be the correct size

//changing the hitbox here
this.sprite.setBody({
      type: 'rectangle',
      width: 600, //can do whatever width or height you want
      height: 50
});

//add functions to the sprite that will affect the hitbox AFTER changing the hitbox
this.sprite.setAngle(angle);
this.sprite.setStatic(true);

```
