* @class vtkDynamic2DLabelMapper
* @brief draw text labels at 2D dataset points
*
* vtkDynamic2DLabelMapper is a mapper that renders text at dataset
* points such that the labels do not overlap.
* Various items can be labeled including point ids, scalars,
* vectors, normals, texture coordinates, tensors, and field data components.
* This mapper assumes that the points are located on the x-y plane
* and that the camera remains perpendicular to that plane with a y-up
* axis (this can be constrained using vtkImageInteractor).
* On the first render, the mapper computes the visiblility of all labels
* at all scales, and queries this information on successive renders.
* This causes the first render to be much slower. The visibility algorithm
* is a greedy approach based on the point id, so the label for a point
* will be drawn unless the label for a point with lower id overlaps it.
*
* @warning
* Use this filter in combination with vtkSelectVisiblePoints if you want
* to label only points that are visible. If you want to label cells rather
* than points, use the filter vtkCellCenters to generate points at the
* center of the cells. Also, you can use the class vtkIdFilter to
* generate ids as scalars or field data, which can then be labeled.
