Ah, I had the slight suspicion...

Yes, that was my thought here. If the classes work, it may be not too hard

If reading a JSON already works, transforming alt/az text lists to JSONs
should be simple enough for users. Which one is the best to use?
Another thought involves sampling the landscape texture if it is
transparent at a location. (It may allow better true-landscape sunrise
etc. predictions) Can this be done via a StelTexture?
