Interpolation/Cosine/Rotation

Summary

Function: rotation rCos( rotation x, rotation y, float t );

Spherical-Cosine interpolation between two rotations.
Returns a rotation

• rotation	x
• rotation	y
• float	t

Specification

<lsl>rotation rCos(rotation x, rotation y, float t){

   float f = (1-llCos(t*PI))/2;
   float ang = llAngleBetween(x, y);
   if(ang > PI) ang -= TWO_PI;
   return x * llAxisAngle2Rot(llRot2Axis(y/x)*x, ang*f);
