/**
 * @class   vtkBlankStructuredGrid
 * @brief   translate point attribute data into a blanking field
 *
 *
 * vtkBlankStructuredGrid is a filter that sets the blanking field in a
 * vtkStructuredGrid dataset. The blanking field is set by examining a
 * specified point attribute data array (e.g., scalars) and converting
 * values in the data array to either a "1" (visible) or "0" (blanked) value
 * in the blanking array. The values to be blanked are specified by giving
 * a min/max range. All data values in the data array indicated and laying
 * within the range specified (inclusive on both ends) are translated to
 * a "off" blanking value.
