title: Do I have the right understanding of frames and bounds in UIKit?
body: <p>Let me try to explain it. Please tell me if I am wrong. I am just 70% sure about it.</p>
  
  <p>Like I understand it, an UIView has a frame and an bounds rectangle.
  The job of the frame rectangle is to set the position of the UIView relative to it's superview. More precisely: Relative to the coordinate system of the superview. The job of the bounds rectangle is to set the drawing area of the UIView, relative to it's own coordinate system.</p>
  
  <p>Briefly:</p>
  
  <ul>
  <li>frame rectangle is for positioning the UIView relative to its superview</li>
  <li>bounds rectangle is to set the drawing area of the UIView</li>
  </ul>
  
  <p>Are there any mistakes or important things I missed?</p>
