Just scale the form prior to using it: `(ImageMorph newWith: (ImageMorph 
defaultForm magnifyBy: 0.5)) openInWorld.`

A new kind of morph that is not part of the BoxMorph hierarchy would 
give better flexibility, by not using an `extent` instance variable. But 
may be the simplest solution works for you.
