#include <allegro.h>
void quat_interpolate(const QUAT *from, const QUAT *to, float t, QUAT *out);
DESCRIPTION
Constructs a quaternion that represents a rotation between from and to.
The argument t can be anything between 0 and 1 and represents where
between from and to the result will be. 0 returns from, 1 returns to, and
0.5 will return a rotation exactly in between. The result is copied to
out. This function will create the short rotation (less than 180 degrees)
between from and to.
