Hi Hans-Martin,

My intention was to always initialize baseColor, because nil was used as a 
substitute of Color transparent back and forth for seemingly no reason.
I must have overlooked those #trackColorFrom: methods, and I think 
replacing ifNil: with isTransparent ifTrue: in them is the right fix.
If you have a better solution in mind, let me know. Or I'll push the above 
fix this week to the Trunk.
