25 * The Quad class specifies a (possibly affine transformed) rectangle.
27 * A Quad instance holds 4 points that define its shape. The points may represent any rectangle that
32 * Each point in the Quad represents a specific corner of the Quad. These are top-left, top-right,
33 * bottom-left, and bottom-right. These labels allow mapping a transformed Quad back to an up-right
