@tana Thanks for the fix! I'm wondering what I was doing with that code and what was the intention of that function... |

Description
This PR fixes calculation of
QuaternionScalefunction inraymath.h.Problem
I found the previous implementation of
QuaternionScalewas calculating(w+ix+jy+kz)(s+is+js+ks), rather than usual quaternion-scalar multiplication(w+ix+jy+kz)s.Solution
Changed the function to calculate
(w+ix+jy+kz)s = ws+i(xs)+j(ys)+k(zs).(Sorry for hard-to-read math, because GitHub does not allow LaTeX equations)
