While this may be worth revisiting, we should first quantify the benefits and
identify the compilers that support it. Ultimately, we may never use pragma
once in favor of strictly using standard C++.
For face-varying interpolation, sharpness should be interpreted as an
infintely sharp boundary. Hbr implements this correctly for vertex
sharpness, but inconsistently for edge sharpness: both the fvarbits
cache and methods that gather face-varying sharpness need to be corrected.

while retaining a necessary 1-ring on the inside of a hole edge
- add IsInsideHole() function to HbrHalfEdge
- add HasChild() function to HbrVertex and HbrHalfedge
- add a regression shape with adjacent holes and creases (tests dart, crease & boundaries)
Note : this does not address hierarchical edits inside holes or hole tags in hierarchical edits
fixes#78
- still need to change these changes with other compilers (MSVC / clang...)
- had to add a -Wno-invalid-offsetof for GCC (still need to test w/ other compilers) : apparently gcc 4.4 is somewhat incorrect in tagging our templated class as POD.
- had to change fvarData.h to initialize bitfields to 0 as gcc generates truncated int warnings when trying to initialize 31 bits to -1
- in mesh.h replaced original tbb::concurrent_vector with std::vector until a better solution can be found
Fixes#93
- [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...
output iterators instead of std::vector - eases prman integration
for cases where std::list makes more sense.
Block allocate face children array in common case (<= 4 children).
Other, minor consistency edits.
