I think this is the only definition that makes sense for a deep rendering stack.
No absolute coordinates. Someone should clarify this in the wiki.

I would say that, whenever a size is given, this can only mean cropping. 
Resizing might not make sense for some filters, like a filter that generates
an infinite pattern.
