Infinite canvas is used AFAIK only in Karbon and in Krita.
It was not INFINITE before in Krita, I implemented this type of canvas for 
Krita in GSoC 2009. I was inspired by code in Karbon.

Basically this type of canvas means that the borders are part of the canvas 
and that the events are coming to the tools. Because before there was QWidget 
(borders, maybe KoCanvasController or something like that) inside QWidget 
(canvas, paint area or I don't know how to name it -- viewport maybe).

I think that is the whole point of Infinite type of canvas, as I remember it. 
Do you need more information?
