// .NAME vtkTreeMapLayoutStrategy - abstract superclass for all tree map layout strategies
//
// .SECTION Description
// All subclasses of this class perform a tree map layout on a tree.
// This involves assigning a rectangular region to each vertex in the tree,
// and placing that information in a data array with four components per
// tuple representing (Xmin, Xmax, Ymin, Ymax).
//
// Instances of subclasses of this class may be assigned as the layout
// strategy to vtkTreeMapLayout
//
// .SECTION Thanks
// Thanks to Brian Wylie and Ken Moreland from Sandia National Laboratories
// for help developing this class.
