[Jay Taoko]

This branch introduces "Redirected Views" in Nux. Redirected views allows a view to be rendered inside its own texture and that texture is latter composited inside the main rendering.
This branch contains the required changes for redirected views. The opportunty was also taken to fix minor issues and introduce API changes.

== Core of the Redirected View
  Nux/Area.cpp
  Nux/Area.h
  Nux/Layout.cpp
  Nux/Layout.h
  Nux/View.cpp
  Nux/View.h

== Fixed ClientArea to work with RedirectedViews
  Nux/ClientArea.cpp
  Nux/ClientArea.h

== Concrete implementation of a view to replace InputArea in some locations
  Nux/BasicView.cpp
  Nux/BasicView.h

== Nux.h contains the Feature.h file of Nux
  Nux/Nux.h

== API change to frame buffer object architecture
  NuxGraphics/IOpenGLFrameBufferObject.cpp
  NuxGraphics/IOpenGLFrameBufferObject.h

== Added InitSlTexturePremultiplyShader shader
  NuxGraphics/RenderingPipeGLSL.cpp
  NuxGraphics/GraphicsEngine.cpp
  NuxGraphics/GraphicsEngine.h
  NuxGraphics/RenderingPipeAsm.cpp

== Fixed texture inversion

[Neil J. Patel (njpatel)]

Been testing this for over a week and works well. Diff is larger as there is API clean up too, but the guts aren't crazy and i've been over them a few times. Tests for the work are covered in the Unity branch that uses them (https://code.launchpad.net/~unity-team/unity/unity.dash-to-preview/+merge/124664). Approved.
