Well, the camera does not do wierd flips anymore, but it is oriented wrong
Made some naming changes for the prev and current coordinate systems for level 4.
Vert Basic Cross Section line drawing algorithm completed.

Now I need to draw as rectanges and recursively -- as with the spline
itself.
Basic Rectangle Drawing algorithm for the track cross section seems to work.  Now all I need to do is make it iterate over more points
Got the Rail Drawing algorithm to work.  Now all I need to find out is how to correctly align my coaster.
Changed some colors and cleaned up the drawing algorithm a little bit so less things were drawn
