I'm student of image processing and we are taught that Strings, no matter how 
they are implemented, are in the end expensive in image processing. I never 
seen them in code which aims to be fast (OpenGL, OpenCV,...).

But I don't say we should rewrite Krita and throw away QString, I just would 
not use them for comparison in loops etc. And the loops can be hidden pretty 
much, you can't say that this or that code will not be in a loop in the end. 
The reason? Because of complexity of Krita and image processing in general.
