r3

Back to true gauss because the recursive is causing some issues with video.
@trickyhunter3 thanks for the report.

r2 - bugfix

• Fix make_positive_xyb which had an outdated formula, and was the main reason for the difference in the result.
• Change gauss to recursive, which reduces the difference in score to something very small.
• Optimizes memory allocation, so even using another gauss this version isn't slower than the previous one.
