I am familiar with that practice <s>.

I was just explaining that I think what you're seeing has a cause we can probably guess at.

Basically, top and left have to be calculated in a a way that is relative to the parent container. When there are fractions involved in the calculations, obviously some extra calculation has to be done. This extra calculation would have to be not only relative to the container but also take its scalemode into account. You can't position something at a fractional pixel (I think you can in foxels, but frankly I can't even remember how this works!!).

So, you see what I'm driving at here?
