Tests if a triangle overlaps a box (AABB). This is the optimized SIMD code.
WARNING: the function has various SIMD requirements, left to the calling code:
- function will load 4 bytes after 'center'. Make sure it's safe to load from there.
- function will load 4 bytes after 'extents'. Make sure it's safe to load from there.
- function will load 4 bytes after 'p0'. Make sure it's safe to load from there.
- function will load 4 bytes after 'p1'. Make sure it's safe to load from there.
- function will load 4 bytes after 'p2'. Make sure it's safe to load from there.
If you can't guarantee these requirements, please use the non-SIMD reference code instead.
