Embree v2.2.0

• Support for motion blur on Xeon Phi
• Support for intersection filter callback functions
• Support for buffer sharing with the application
• Lots of AVX2 optimizations, e.g. ~20% faster 8-wide hybrid traversal
• Experimental support for 8-wide (AVX/AVX2) and 16-wide BVHs (Xeon Phi)

Embree v2.1.0
