Wee! Good to hear from you again.

I think you main point of confusion is this: the colorspace class does not do 
anything to the canvas. Krita grabs a pointer to a memory-contiguous set of 
pixels from the canvas and then gives this pointer to the colorspace to work 
on. So, the functions in a colorspace work on relatively small runs of pixels 
(or even single pixels).
