The min spec is SSSE3, using SSE4.1 instructions (_mm_extract_epi64) will break compatibility. The code containing the defect is debug only, and %90+ of the user base uses an SSE4.1 capable processor.
* Use mathlib SIMD wrappers instead, this is to maintain compatibility across different platforms/compilers.
* Moved camera distance logic to separate method.
* Make box's mins and maxs static const.
* Use SSE to pack 4 indices into 1 128bit register, and shuffle to prevent duplication. Only 2 indices are used at the moment.
* Construct min/max for AI Script Network boxes using SIMD (significantly reduced instruction count!).
* Move NavMesh debug draw to dedicated class for future changes.
* Move AIN/NavMesh debug draw to ai_utility_shared.cpp.
* Use shift index + range for AIN debug draw.
* Added cvar for determining max distance between camera and tile (anything outside this range doesn't get draw).
