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