    // This is a cool one, so the crosshair png is too big so we're only using 25% of its original size

    // But then we need center point of the new rect to rotate it accurately
    // So we divide the og size by 8
    // So now you ask: Wouldn't it be easier to just shrink the png?
    // My response: nuh huh
