/**
* We have to disable a couple of tests here for the case when
* vastScrolling value is 0.2. The problem is that the centering
* correction applied to the offset in
* KisCanvasController::rotateCanvas pollutes the preferredCenter
* value, because KoCnvasControllerWidget has no access to this
* correction and cannot calculate the real value of the center of
* the image. To fix this bug the calculation of correction
* (aka "origin") should be moved to the KoCanvasControllerWidget
* itself which would cause quite huge changes (including the change
* of the external interface of it). Namely, we would have to
* *calculate* offset from the value of the scroll bars, but not
* use their values directly:
*
* offset = scrollBarValue - origin
*
* So now we just disable these unittests and allow a couple
* of "jumping" bugs appear in vastScrolling < 0.5 modes, which
* is, actually, not the default case.
