// .NAME vtkShader2 - GLSL Shader
// .SECTION Description
// A vtkShader2 object is made of a source code encoded into a string and
// a type, identifying the hardware programmable stage it is attached to.
// Hardware programmable stages are (or will be)
// 1. vertex shader
// 2. tessellation control shader
// 3. tessellation evaluation shader
// 4. geometry shader
// 5. fragment shader
//
// Note: tessellation control shader is called hull shader in DirectX11
// Note: tessellation evaluation shader is called domain shader in DirectX11
