// .NAME vtkSMBoundsDomain - double range domain based on data set bounds
// .SECTION Description
// vtkSMBoundsDomain extends vtkSMDoubleRangeDomain to add support to determine
// the valid range for the values based on the dataset bounds. There are several
// \c Modes which can be used to control how the range is computed based on the
// data bounds (defined by the vtkSMBoundsDomain::Modes enum).
// \li \c NORMAL : this is the basic mode where the domain will have 3 ranges which
// are the min and max for the bounds along each of the coordinate axis.
// \li \c MAGNITUDE: the domain has a single range set to (-magn/2.0, +magn/2.0)
// where magn is the magnitude of the diagonal.
// \li \c ORIENTED_MAGNITUDE: same as MAGNITUDE, but instead of the dialog, a
// vector determined using two additional required properties with functions
// Normal, and Origin is used.
// li \c SCALED_EXTENT: the range is set to (0, maxbounds * this->ScaleFactor)
// where maxbounds is the length of the longest axis for the bounding box.
// li \c APPROXIMATE_CELL_LENGTH: approximation for cell length computed using the
// li \c DATA_BOUNDS: this mode for a 6 tuple property that takes the data
// bounds. The range will have 6 ranges:
// (xmin,xmax), (xmin,xmax), (ymin,ymax), (ymin,ymax), (zmin,zmax), and (zmin,zmax).
// If default_mode is not specified, then "min,max,min,max,min,max" is assumed.
// li \c EXTENTS: this mode for a property that takes a value between 0 and (max-min) for
// each component.
//
// To determine the input data bounds, this domain depends on a required
// property with function \c Input. The data-information from the source-proxy
// set as the value for that property is used to determine the bounds.
//
// Supported XML attributes:
// \li \c mode : used to specify the Mode. Value can be "normal", "magnitude",
// "oriented_magnitude", "scaled_extent", or "approximate_cell_length", "data_bounds".
// \li \c scale_factor : used in SCALED_EXTENT and APPROXIMATE_CELL_LENGTH mode.
// Value is a floating point number that is used as the scale factor.
