NAME
quat_interpolate - Constructs a quaternion representing a rotation
between from and to. Allegro game programming library.
SYNOPSIS
#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.
