They have been there all the time. :o)
I'm not sure of the reason for these float-based Rects, but I suppose Kurt
chose them because it made the layout classes simpler to implement...
Is there any real reason why we should replace them with integer versions?

Very true. (it is very confusing) :o)

I don't think we should change this (after all, it is correct)... Maybe a
PixelWidth()/Height() method would be a good idea?
