title: Prevent insertText from placing text on previously inserted text?
body: <p>I have a picture, for which I have the x and y coordinates for multiple objects. Each object has a name. I wish to use insertText to place the name in the middle of the object. Considering the large amount of objects per image, sometimes the text overlaps. </p>
  
  <p>Currently, i use this which writes the text exactly to the middle.</p>
  
  <pre><code>I = imread(some_image.jpg);            % load image
  for i = 1:length(object)               % for each object
      m = mean(object(i,1:2)));          % get the middle 
      I = insertText(I,m,[name]);        % and write label. 
  end
  </code></pre>
  
  <p>What I want is a new label to be moved slightly, so that the newest label does not overlap with an old label. </p>
