### Description

This is an adaptation of the VTK test [clipArt.tcl](http://vtk.org/gitweb?p=VTK.git;a=blob;f=Graphics/Testing/Tcl/clipArt.tcl;h=85a39f9821b999145119a5a8ca492a6ae705ed09;hb=HEAD). Provide a jpg file with 2D clipart and the example will create 3D polydata model. The examples illustrates a number of VTK classes including vtkImageThreshold, vtkImageSeedConnectivity, vtkDecimatePro and vtkClipPolyData.

The example assumes that the image has a white background. Try it with this `src/Testing/Data/stormy.jpg`.
