Very good. However, you're now doing a lot of complicated manual
placements and numbers. Just noting this for the record.

No, my code goes to spec-- though I concede the point that the spec may
not have been stated clearly.

Your code has the total height of B(the entire right column) being X;
and G is one third of that total height, while H is 2/3'ds of it. That's
close, but very specifically not what I was going for.

I was going for B having a total height of "X"; and that H is 300% the
size of G, as demonstrated in the following:

You should be able to see that your "G" is half the size of "H", where
mine is one third of its size. If you dispute this assertion, I can
provide exact measurements to demonstrate, but it should be visually clear.

But, that said: You're very close, close enough to satisfy the
challenge. But that's an easy one.

I now present you the following alterations to the existing spec:

  - A must be a set, fixed size of 100x20.
  - H must expand fully, but maintain its aspect ratio.

Now, in addition, in my code I made it so I could add as many new items
to the top half of the left-column, and not require any tweaking of
other things. This way, it can elegantly be expanded. The "F" panel
which must be the bottom 50% doesn't ever need to be modified-- I simply
add more things to the top half and it adjusts accordingly.

A few tiny modifications to the existing code is at:
