velocityCurve

[Starglider]

I was looking through various engine cfg files, and noticed something I didn't understand.

The velocityCurve section has several keys. I understand that the first number references the speed at which the key applies, and I understand that the second number is a thrust limiter for that speed.

What I don't understand, are the last two numbers in each key (typically 0s, but I've seen other numbers in some of the B9 cfgs). What are those numbers supposed to do?

They're tangents. Here's how they're used.
