This commit basically vectorizes existing code using AVX2 instructions (without modifying algorithm itself). This gives quite nice speedups: BMW: -8% Classroom: -5% Cat: -5% Koro: +1% Barcelona: -8% That's on Linux machine, reported performance improvement on Windows goes up to 20%. Not currently sure why Koro is somewhat slower because it mainly uses curve intersection tests, could be a time noise? Or osmething with the cache utilization perhaps? In any case speedup in other scenes makes me thinking that current state is acceptable for initial implementation. This is again inspired by Maxym Dmytrychenko.
