[vtkusers] Fill polygons with internal holes

[oyster]

Hi, Ondrej
If you mean color the individual polygon, you may try:
1. Identify each polygon with vtkPolyDataConnectivityFilter 
2. Determine overlapping order through Boost::Geometry::Polygon, for example

3. I presume your polygons are in 2D space since they are embedded each
other, 
through OVERLAPPING tests you can assign each polygon with a virtual Z
coordinate
denoting depth order, and then let vtkDepthSortPolydata doing the rest
rendering works.
