 105  * This is a demonstration of how to use the projection library. A projection
 106  * creates a mutation of the coordinates of all the points in the model, creating
 107  * virtual x,y,z coordinates. In effect, this is like virtually rotating the entire
 108  * art car. However, since in reality the car does not move, the result is that
 109  * it appears that the object we are drawing on the car is actually moving.
 110  *
 111  * Keep in mind that what we are creating a projection of is the view coordinates.
 112  * Depending on your intuition, some operations may feel backwards. For instance,
 113  * if you translate the view to the right, it will make it seem that the object
 114  * you are drawing has moved to the left. If you scale the view up 2x, objects
 115  * drawn with the same absolute values will seem to be half the size.
 116  *
 117  * If this feels counterintuitive at first, don't worry. Just remember that you
 118  * are moving the pixels, not the structure. We're dealing with a finite set
 119  * of sparse, non-uniformly spaced pixels. Mutating the structure would move
 120  * things to a space where there are no pixels in 99% of the cases.
