+ * This is a demonstration of how to use the projection library. A projection

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