 112  * This is a demonstration of how to use the projection library. A projection
 113  * creates a mutation of the coordinates of all the points in the model, creating
 114  * virtual x,y,z coordinates. In effect, this is like virtually rotating the entire
 115  * art car. However, since in reality the car does not move, the result is that
 116  * it appears that the object we are drawing on the car is actually moving.
 117  *
 118  * Keep in mind that what we are creating a projection of is the view coordinates.
 119  * Depending on your intuition, some operations may feel backwards. For instance,
 120  * if you translate the view to the right, it will make it seem that the object
 121  * you are drawing has moved to the left. If you scale the view up 2x, objects
 122  * drawn with the same absolute values will seem to be half the size.
 123  *
 124  * If this feels counterintuitive at first, don't worry. Just remember that you
 125  * are moving the pixels, not the structure. We're dealing with a finite set
 126  * of sparse, non-uniformly spaced pixels. Mutating the structure would move
 127  * things to a space where there are no pixels in 99% of the cases.
