/// **Notice these docs are heavy WIP and not very relevent yet**

/// A point is specified by a x coordinate and an y coordinate which
/// can be accessed using the x() and y() functions. The isNull()
/// function returns `true` if both x and y are set to 0. The
/// coordinates can be set (or altered) using the setX() and setY()
/// functions, or alternatively the rx() and ry() functions which
/// return references to the coordinates (allowing direct
/// manipulation).
///
/// Given a point *p,* the following statements are all equivalent:
///
/// A QPoint object can also be used as a vector: Addition and
/// subtraction are defined as for vectors (each component is added
/// separately). A QPoint object can also be divided or multiplied by
/// an `int` or a `qreal.`
///
/// In addition, the QPoint class provides the manhattanLength()
/// function which gives an inexpensive approximation of the length of
/// the QPoint object interpreted as a vector. Finally, QPoint objects
/// can be streamed as well as compared.
