title: Get Layout Shape Corresponding to Slide Shape
body: <p>In PowerPoint 2007 and using VBA, how can I get the placeholder shape on a Slide Master layout that is the "master" for a placeholder shape on the slide?</p>
  
  <p>I am currently using a loop to compare the position and size of the slide placeholder with the position and shape of each placeholder shape in the slide's layout, but this isn't fool-proof.  For example, if the placeholder shape is moved on the slide, its position may no longer match the position of any placeholder shapes in the slide's layout.  I could reapply the slide's layout to snap placeholders back into position, but that's not what I want to do.</p>
  
  <p>Something in the object model like <code>Shape.Master</code> would be ideal but, of course, that doesn't exist.</p>
