title: Is it possible to downscale depth texture on Metal?
body: <p>I want to downscale depth texture to half of it width and height and then attach to smaller render buffer for continue rendering.</p>
  
  <p><code>MTLPixelFormatDepth32Float</code> is read only format for compute shaders. </p>
  
  <p>I wonder if any of those are possible:</p>
  
  <ol>
  <li>Blit from R32 to Depth32</li>
  <li><code>MPSImageLanczosScale</code> with Depth32</li>
  </ol>
  
  <p>Or maybe there is another solution? </p>
