[Drawkit] Changing margins does not shift drawing objects

[Graham Cox]

Turns out this is a bit more involved than it seemed at first. I do  
think it should be done this way, but to save time I've done it by  
using the "changed margins" notification to shift the objects for now.  
I've added a method that will iterate over the objects and apply a  
transform to each - applications could use this to perform scaling if  
they wanted. I'm using this method to implement the margin shift.

I'll work in a proper solution when there's more time to do it.

cheers, Graham
