 @abstract
 An instance of `FBProfilePictureView` is used to display a profile picture.  
 
 The default behavior of this control is to center the profile picture
 in the view and shrinks it, if necessary, to the view's bounds, preserving the aspect ratio. The smallest
 possible image is downloaded to ensure that scaling up never happens.  Resizing the view may result in 
 a different size of the image being loaded.  Canonical image sizes are documented in the "Pictures" section
 of https://developers.facebook.com/docs/reference/api.
