/*!
    \class QVector2DArray
    \brief The QVector2DArray class is a convenience for wrapping a QArray of QVector2D values.
    \since 4.8
    \ingroup qt3d
    \ingroup qt3d::arrays

    QVector2DArray is used to build an array of 2D vector values
    based on floating-point x and y arguments:

    \code
    QVector2DArray array;
    array.append(1.0f, 2.0f);
    array.append(-1.0f, 2.0f);
    array.append(1.0f, -2.0f);
    \endcode

    This is more convenient and readable than the equivalent with
    QArray:

    \code
    QArray<QVector2D> array;
    array.append(QVector2D(1.0f, 2.0f));
    array.append(QVector2D(-1.0f, 2.0f));
    array.append(QVector2D(1.0f, -2.0f));
    \endcode

    QVector2DArray also has convenience functions for transforming
    the contents of the array with translate(), translated(),
    transform(), and transformed().

    \sa QArray, QVector3DArray, QVector4DArray
