I'd guess so. For example, the class comment is quite misleading as no
caching is done anymore. The instvars colorArray and colorDepth can be
removed because they're unused.

What might be challenging (maybe it's easy) is making the World be able to
have a gradient - PasteUpMorph actually is a subclass of GradientFillMorph
but it's drawOn: method is only used in a Playfield, not for the World.

But maybe the class can be removed entirely since we now have
GradientFillStyles and don't need that special Morph anymore ...
