* added the numVertexElements argument to Osd*DrawContext::Create, which is used to initialize the patch arrays when calling OsdDrawContext::ConvertPatchArrays
* removed the unused level argument from Osd*DrawContext::_initialize
* maintenance work on CL/D3D11 bindings to get them to compile

and adding the requisite accessors
Note : all our example code goes through the same boiler-plate texture
binding code - we might want to move it as a member function of the DrawContext.
- 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.
fixes#143
- add bool OsdGLDrawContext::SupportsAdaptiveTessellation() method
- modify glViewer to use that instead of #ifdefs
Note : this is not the final word on this as OSD really needs a more comprehensive
system to provide run-time information about available features to the client code.
fixes#111
- remove the GL error check in cudaGLVertexBuffer :
* unrelated GL errors left on the stack were triggering erroneous
vertexBuffer allocation errors
* we should not be checking for GL errors here anyway (as most other
buffer allocations aren't checked either)
- add some pointer checking in the GL / D3D drawContexts in case the
vertexBuffer pointers passed are NULL
- add some additional typedefs in OsdError to report some of the new
CUDA / GL related errors
- [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...
