Description:
  Objects can have per viewport display properties
  that override a viewport's default display
  properties.  These overrides are stored on 
  ON_3dmObjectAttributes as a list of 
  ON_DisplayMaterialRefs.
  
Example:
  For example, by default a viewport
  might display objects using a wireframe, but
  one special object may need to be shaded.
  In this case the special object would have
  a display material ref with the "wireframe"
  viewport's id and the id of a display material
  that specified shading.
