[vtkusers] ANN: VTKExamples adds Shader example

[Bill Lorensen]

We are excited to announce that we have added several examples that
show how to use vtkShaders to generate exciting images. Each of the
new examples modifies the existing vtkOpenGLPolyData pipeline. We hope
that these examples will stimulate interest and usage of this advanced
capability.

The new examples are here:

As always we ask you to contribute to the grassroots effort to make
VTK more understandable and exciting.
See: https://lorensen.github.io/VTKExamples/site/Instructions/ForDevelopers/

Andrew Maclean and I will be happy to get you started.

Stay tuned, we will be adding more examples in the next weeks.
