OpenSubdiv/regression/osd_regression/main.cpp
manuelk 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...
