[UI] FillStyles in borders

[Gary Chambers]

Perhaps a "clean" model coul;d be something for Pharo...

Maybe borders could be modelled via a decorator pattern to do away with some of these special cases.
(think fillWith: fillStyle clippingTo: generalClipShape)The border (itself a morph) being a decoration of the morph... or maybe not called morph in a generalised framework, though interpreted that way for Morphic support...

Then again, to go the full-hog, the "ordinates" idea should cover all bases (with adaptation to Morphic).

Just a thought.

Gary.
