  Implemented varying packing
  TRAC #11736
  The OpenGL ES Shading Language 1.00 rev. 17 appendix A section 7 page 111, details how varyings should be packed into generic varying registers. To implement this the HLSL main() function is now generated and appended to the code during link time, where the packing and mapping can happen.
