For *most* purposes they are the same, but 0!=null, and there are cases
where that is important. There are lots of places in the DynAPI2 code
that test specifically for null for a reason. Especially when testing
width, height, x, y types of values, where zero is a valid value, but a
null value isn't.

It's all a matter of context for the variable being examined.
