Subject: GLAutoDrawable: Refine API doc; Use new abstract impl.
 GLAutoDrawableBase (GLWindow, ..); Add new GLAutoDrawableDelegate.

- Refine API doc
  - 'void setContext(GLContext)' -> 'GLContext setContext(GLContext)'
  - Add note to createContext(GLContext) override

-Use new abstract impl. GLAutoDrawableBase, used by:
  - GLWindow
  - GLAutoDrawableDelegate
  - GLPbufferImpl

- Add new GLAutoDrawableDelegate incl. unit test
