title: Display image at desired scale across subplot axes
body: <p>Is it possible to display an image in multiple subplot axes, such that the image appears at the desired scale?</p>
  
  <pre><code>subplot(3,3,[1 4 7]);
  %# image scaled down to fit 1 set of axes
  imshow(img);
  subplot(3,3,2);
  plot(relevantData);
  %# And so on with 5 other plots
  </code></pre>
  
  <p>I want to have the image scaled to either a fixed size or to fit the axes available to it, rather than to the size of a single axes.</p>
  
  <p>My use case is to show a video alongside plots derived from the video, such that the plots are progressively drawn in step with the video. Once the display is correct I can save each image and combine them into a video.</p>
  
  <p><strong>Clarification</strong></p>
  
  <p>I am asking if it is possible to produce a figure as described <em>without</em> specifying the position of every element in absolute terms.  Though one can make arbitrary figures that way (and in fact I have done so for this project), it is <em>very</em> tedious.</p>
