When writing widgets, I've found that every single widget has to
test for the reverseVideo attribute in the Initialize function and
reverse the values of the background and foreground colors, or this
doesn't seem to happen automatically.  What's worse, the result seems
to be unpredictable (mostly due to lack of adequate testing :-).

It would be nice if the toolkit intrinsics noticed this and swapped
those colors for you, but alas, not every widget has a foreground
color (most do).

At any rate, I was wondering if someone else knows how to better
deal with this.  Also, are there any other attributes that have to
be dealt with similarly?
