[fix] 2D Rocket Figure will now display off-axis CoM and CoP

[teyrana]

This does NOT affect any calculations -- it just more accurately displays those same values on the 2D view.

This also means that 2d views and 3d views display these values more similarly.

Hey @teyrana,
Your changes look good to me!

I think you're right, we need to do this -- we may decide to pin the CP to Y=Z=0 in some (most?) cases, but the figures need to show whatever we end up calculating.

But, in 2D view, as I rotate the rocket the CP stays stationary instead of rotating with the rocket.

[JoePfeiffer]

This isn't rotating the CP with the rocket -- with the attached design (which is the off-axis CP example I created before with the nose cone removed so the CP is really off axis) the CP just sits at the top of the body tube as the rocket is rotated.

(display now respects the rotation slider)

That's got it. My vote is we merge this so we actually see what we're calculating (whatever that turns out to be).
