All tracker are aggregated in the GLContext now

and used within the GL*Impl.

New GLStateTracker:
    - Tracking client/server states
    - Currently supports PixelStorei
    - Prologued in glPixelStorei and glGetIntegerv,
      the latter will return the tracked state if available
      and not call the GL method.
      Impacts performance and ES1 compatibility (supports ALIGNMENT).

Fixed 'imageSizeInBytes' calculation:
    - skipPixels and skipRows is a static one time offset
