// .NAME vtkGLSLShaderProgram - GLSL Shader Program
// .SECTION Description
// vtkGLSLShaderProgram is a concerete implementation of vtkShaderProgram.
// It's main function is to 'Link' a vertex and a fragment shader together
// and install them into the rendering pipeline by calling OpenGL2.0.
//
// Initialization of shader parameters is delegated to instances of vtkShader
// (vtkGLSLShader in this case).
// .SECTION Thanks
// Shader support in VTK includes key contributions by Gary Templet at
// Sandia National Labs.
