- Added OSD_ prefix to preprocessor symbols

consistent with non-transition patches
- Unified BSpline shader code

- Fixed a few discrepancies in the remaining duplicate code paths
- [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
