Comment 7 for bug 301075

I have applied a fix similar to the one that was suggested in https://bugs.launchpad.net/ubuntu/+source/gtk+2.0/+bug/479810, which fixed the positioning of the drawing in mypaint, but also broke pressure sensitivity

Applying that fix however only helped for mypaint and gimp, but not for krita. THis gives me the idea the problem might even be more generic?
