\since 5.6
\brief A PropertyAnimation for quaternions.
A specialized \l{PropertyAnimation} that defines an animation between two
\l{QQuaternion}{quaternions}.
By default spherical linear interpolation is used. This can be changed to
the faster but less accurate normalized linear interpolation by setting the
\a type property.
Instead of specifying quaternions directly in the \a from and \a to
properties, it is also possible to provide euler angles in degrees in the
\a fromXRotation, \a toXRotation, \a fromYRotation, \a toYRotation,
\a fromZRotation, \a toZRotation properties.
\note Avoid mixing the quaternion and euler angle-based properties. The
from and to values are expected to be fully specified either via a
quaternion or the three euler angles.
