  WGL implemetation for OpenGL tutorial
  
  Fixes to make WGL implementation work with OpenGL tutorial
  - Give directive parser the correct shader spec when on Desktop GL
  - Minor changes to parse Desktop GL shaders
  - Moved clientType parameter from Context to Context->mState
  - Minor fixes to WGL functions
