 * handle the I/O communication between the <code>vtkImageData</code> and the GPU Texture using fully the VTK shader infrastructure, since the shader infrastructure is already available in VTK (safe binding, automatic versioning, etc... http://www.vtk.org/Wiki/Shader_In_VTK).
 * child classes will handle different approach (e.g. multipass/iterative filtering).
