* You can modify the size of the physics Body to be any dimension you need.
* So it could be smaller or larger than the parent Sprite. You can also control the x and y offset, which
* is the position of the Body relative to the top-left of the Sprite.
* This allows you to make it smaller, or larger, than the parent Sprite.
* You can also control the x and y offset of the Body. This is the position of the
* Body relative to the top-left of the Sprite _texture_.
*
* Calling `setSize` will have no effect if you have previously used `Body.setCircle`. To change a collision
* circle use `setCircle` instead.
* For example: If you have a Sprite with a texture that is 80x100 in size,
* and you want the physics body to be 32x32 pixels in the middle of the texture, you would do:
*
* `setSize(32, 32, 24, 34)`
*
* Where the first two parameters is the new Body size (32x32 pixels).
* 24 is the horizontal offset of the Body from the top-left of the Sprites texture, and 34
* is the vertical offset.
*
* @method Phaser.Physics.Arcade.Body#setSize
* @param {number} width - The width of the Body.
* @param {number} height - The height of the Body.
* @param {number} [offsetX] - The X offset of the Body from the Sprite position.
* @param {number} [offsetY] - The Y offset of the Body from the Sprite position.
* @param {number} [offsetX] - The X offset of the Body from the top-left of the Sprites texture.
* @param {number} [offsetY] - The Y offset of the Body from the top-left of the Sprites texture.
