Oops, I originally had ramped the vasi/papi color transition the wrong way.

So as you passed through the target glide slope from low to high it would
be colored: red -> white -> small range of transition to red -> white.
Now it goes the right way so you get: red -> smooth transition to -> white.
You can tell you are getting high if you see the bottom vasi start to turn
pink ... etc. etc. hopefully just like in real life.
