no it should return where there are affect _actual_ pixels. Which is why we 
united we the actual pixels of the device when default is not MIN

Two kind of operations can be thought of:
 - do stuff to every pixel selected. As in filling the entire selection.
 - do stuff with selected pixels. As in copying what you have selected

setDirty in your case is of the first kind. For that you need to do some extra 
stuff yourself. Please don't change the method. I however think there is 
another method called something like "does this rect boud everything" that 
you might be able to use (this is off the top of my head though)
