4bab37310d minor clean up of the patch parametric bitfields API
note : this is not using traditional bit-fields as we cannot guarantee that the CPU-side
compiler will match the bit-packing of the compilers used on the GPU-side.

e6e7c96a52 We need to leverage our per-patch ptex indexing scheme in the EvalLimit API.
- replace ptex indexing with the FarPtexCoord structure as a way to pass per-patch
  ptex data to the shaders.

  We are replacing a vector<int> arranged as :
  int[0] : ptex face index
  int[1] : (u,v) as 16 bits encoding the log2 coordinate of the top left corner

  Instead we are now using a struct arranged as :
  int[0] : ptex face index
  int[1] : is a bit-field containing u,v, rotation, depth and non-quad

  The u,v coordinates have been reduced to 10 bits instead of 16, which still
  gives us a lot of margin.

- Replace OsdVertexBufferDescriptor with something more adequate for general
  primvar representation (this name will probably eventually change...)

- Improve OsdPatchDescriptor
    - add a "loop" boolean (true if the patch is of loop type)
    - add a GetPatchSize() accessor

- OsdPatchArray :
    - remove some redundant elements (still more to do there)

- Fix all shader / examples / regressions & stuff to make this all work.

8efecb0fca Batching stuffs: generalized kernel batches, table/dispatcher refactoring, multiMeshFactory, drawContext, etc.
2 client APIs are changed.
- VertexBuffer::UpdateData() takes start vertex offset
- ComputeController::Refine() takes FarKernelBatchVector

Also, ComputeContext no longer holds farmesh.
Client can free farmesh after OsdComputeContext is created.
(but still need FarKernelBatchVector to apply subdivision kernels)

10c687ecd5 Release Candidate 1.0 :
- [Feature Adaptive GPU Rendering of Catmull-Clark Surfaces](http://research.microsoft.com/en-us/um/people/cloop/tog2012.pdf).

- New API architecture : we are planning to lock on to this new framework as the basis for backward compatibility, which we will enforce from Release 1.0 onward. Subsequent releases of OpenSubdiv should not break client code.

- DirectX 11 support

- and much more...
