it is a bit tricky. The #fillRectange:fillStyle: is a double-dispatch entry
actually one could use:

aFillStyle fillRectangle: aRectangle on: self

See a CompositeFillStyle how it works.

The idea was to replace all uses of #doSomething: x color: y
or #doSomething:border:colorA:colorB:

with #doSomething: x fillStyle: y...

Actually all painting operations could take only two objects: shape
and fill style.

So, in this respect, a color property of Morph should be a fill style,
since color can be described as 'solid fill with single color' fill
style,
a most simplest possible one.
