Log Message:
-----------
Possible fix for all the particles related SIMD SVBVH bugs.
* Velocity for particles that were born at exactly integer frames was calculated wrong when they were born.
Note: If you had a raytrace acceleration related bug, please clear the pointcache for all particles, toggle a particle setting to reset pointcache and rebake to create a valid simulation.
