BF-admins agree to remove header information that isn't useful,
to reduce noise.
- BEGIN/END license blocks
Developers should add non license comments as separate comment blocks.
No need for separator text.
- Contributors
This is often invalid, outdated or misleading
especially when splitting files.
It's more useful to git-blame to find out who has developed the code.

The crash was caused by BVH traversal stack being overflowed.
That overflow was caused by lots of false-positive intersections
for rays originating on a non-finite location.
Not sure why those rays will be existing in the first place,
this is to be investigated separately.
This commit moves pre-SSE4.1 check to a higher level function
and enables it for all miroarchitectures.
This means the shader can now be used for procedural texturing. New
settings on the node are Samples, Inside, Local Only and Distance.
Original patch by Lukas with further changes by Brecht.
