Title: Make the moon visible again

For #2791.

This makes all planet billboards the same colour (200,200,200,255). Ideally the colour would depend on lighting (how much of the planet's *lit* side can you see), and planets would have appropriate albedo values. But at least this makes the moon visible again.

Also reduces the billboard size threshold to 8 pixel diameter and fixes the screen-size calculation.
