DESCRIPTION
     2D box which has planes parallel to the major axes and is specified by
     two points (specified as floating point) on a diagonal. This class is
     part of the standard Inventor datatype classes and is used as input and
     output to geometry operations.

METHODS
                         SbBox2f()
                         SbBox2f(float xmin, float ymin, float xmax float
                              ymax)
                         SbBox2f(const SbVec2f &min, const SbVec2f &max)
     void                ~SbBox2f()
          Constructors and destructor for a 2D float box. xmin, ymin, xmax,
          and ymax are the bounds of the box. min and max are the corners of
          the diagonal that define the box.
     const SbVec2f &     getMin()
     const SbVec2f &     getMax()
          Returns the minimum and maximum points of the box.

     SbVec2f             getCenter()
          Returns the center of the box.

     void                extendBy(const SbVec2f &point)
     void                extendBy(const SbBox2f &box)
          Extends this box (if necessary) to contain the specified point or
          other box.

     SbBool              intersect(const SbVec2f &point)
     SbBool              intersect(const SbBox2f &box)
          Returns TRUE if the specified point or box intersects this box.

     void                setBounds(float xmin, float ymin, float xmax, float
                              ymax)
     void                setBounds(const SbVec2f &min, const SbVec2f &max)
          Sets the corners of the box.

     void                getBounds(float &xmin, float &ymin, float &xmax,
                              float &ymax)
     void                getBounds(SbVec2f &min, SbVec2f &max)
          Gets the corners of the box.

     void                getOrigin(float &x0, float &y0)
          Gets box origin.

     void                getSize(float &x, float &y)
          Gets box size.

     float               getAspectRatio()
          Gets box aspect ratio.

     void                makeEmpty()
          Makes an empty box.

     SbBool              isEmpty()
          Returns TRUE if the box is empty, and FALSE otherwise.

     SbBool              hasArea()
          Returns TRUE if both dimensions of the box have positive size, and
          FALSE otherwise.
