I think this a good idea.  I also noted many cases where padding makes 
no sense.

Perhaps PaddedMorph subclass of BoxedMorph?

Subclasses of PaddedMorph might start with:

   ImageMorph
   LabelMorph
   LayoutMorph
   TextParagraphMorph
   InnerTextMorph

Then incrementally migrate:

   HoverHelpMorph
   MenuMorph
   PluggableMorph
   TextParagraphMorph
   TranscriptMorph

This also brings up usage and testing of PlacedMorphs [Non-BoxedMorphs] 
in Layouts.

We have not used this much and the behavior of vector-graphic Morphs 
rescaled by Layouts seem kind of random/uneven.

Perhaps chat on Wednesday?

Would it be OK if I make up a changeSet refactoring the above with 
PaddedMorph ?
