[Cuis-dev] scaling an ImageMorph

[Mark Volkmann]

@Ezequiel Birman <ebirman77 at gmail.com> Instead of sending #openInWorld to
the morph, try this:

SystemWindow new addMorph: morph; openInWorld

You'll see the problem with the big orange area I'm trying to fix. The
orange comes from the defaultColor method of BorderedBoxMorph which is the
superclass of ImageMorph.

I feel like all that should be required is:

morph scaleBy: somePercentage

and it should render without the orange area. Maybe there's a change that
can be made to achieve that.
