This cl splits PixelRoutine into 2 specialized classes:
PixelProgram and PixelPipeline.
In this cl:
- Moved all specialized behavior of PixelRoutine into the
  PixelProgram and PixelPipeline classes.
- Inverted hierarchical dependency between PixelRoutine and
  QuadRasterizer. QuadRasterizer is now the base class.
- Added a check to PixelProcessor::routine() to either create
  a PixelPipeline object or a PixelProgram object.
- Moved a few interpolation related utility functions from
  PixelRoutine down to QuadRasterizer.
- Added Registers hierarchy. PixelProgram specific Registers
  and PixelPipeline specific Registers are now mutually
  exclusive.
- Made the quad functions virtual
- Added a few virtual functions (setBuiltins, ps, alphaTest,
  rasterOperation) for Program/Pipeline specific implementations

feedback varyings gather operation to work properly:
- A basic implementation of
  Program::gatherTransformFeedbackLinkedVaryings()
  has been made as a first step.
- transformFeedbackBufferMode is now initialized in

- transformFeedbackLinkedVaryings are now properly
  reset

Also:
- Removed useless DirectX semantic information from
  the LinkedVarying class
- ++it is more efficient than it++ in a loop, because
  it++ create a temporary object to return the
  original state of the iterator, so I made the
  changes where applicable in Program.cpp.
