Okay -- I'll keep this in mind while coding. I've never seen much harm in 
inheriting data, as long as the inheritance hierarchy is shallow -- but then 
again, I'm more used to Python where the whole idea of what constitutes a 
class is much more fluid.

Perhaps because in languages like Java (although I'm not going to defend that 
language as 'modern' or Python classes are objects in their own right. But 
that's just a guess.

Anyway, I was only scanning previous mails to find that hint on how to 
implement undo/redo for the brush tool, and then I found I hadn't noticed 
this mail before.
