title: VNImageBasedRequest regionOfInterest not within normalized bounds
body: <p>I am attempting to access specific sections of an image to perform a VNCoreMLRequest on user defined areas of the image. I am getting errors for certain regions of interest while others are just fine. Each region is normalized.</p>
  <p>The following two areas work:</p>
  <pre><code>regionOfInterest    CGRect  (origin = (x = 0.49538024164889838, y = 0.31979695431472077), size = (width = 0.26865671641791045, height = 0.24492385786802032))
  
  regionOfInterest    CGRect  (origin = (x = 0.13290689410092396, y = 0.28807106598984761), size = (width = 0.24733475479744135, height = 0.19416243654822332))
  </code></pre>
  <p>But the two following areas don't work:</p>
  <pre><code>regionOfInterest    CGRect  (origin = (x = 0.15422885572139303, y = 0.87563451776649747), size = (width = 0.29992892679459843, height = 0.32106598984771573))
  </code></pre>
  <p>Error message: &quot;The region of interest [0.148543, 0.874365, 0.319829, 0.31599] is not within the normalized bounds of [0 0 1 1]&quot;</p>
  <pre><code>regionOfInterest    CGRect  (origin = (x = 0.57640369580668083, y = 0.90862944162436543), size = (width = 0.24307036247334754, height = 0.36928934010152287))
  </code></pre>
  <p>Could someone point out what I am not seeing? Maybe there is something I am not understanding about the <code>regionOfInterest</code></p>
