Orbit lines not hidden properly by the parent planet

[Shantanu Agarwal]

The arcs of orbit lines coinciding with the planet are either shown through the parent planet or completely hidden by it. Please see the attached screen shots.

Also planets and the sun. See Venus transit of the sun June 6th 2012.

I made a branch that adds depth testing on the orbit lines:

This fixes the problem, but might introduce other bugs. I don't see how else we could do it though.

This patch is good for case planets, but not very good for case moons.
