Associates a \a callback object with this channel mapping.
Such mappings do not have to have a target object and property name. When
the \a callback object is set, every change in the animated value will lead
to invoking the callback's
\l {Qt3DAnimation::QAnimationCallback::valueChanged}{valueChanged} function either
on the gui/main thread, or directly on one of the thread pool's worker
thread. This is controlled by \a flags.
\a type specifies the type (for example, QVariant::Vector3D,
QVariant::Color, or QMetaType::Float) of the animated value. When animating
node properties this does not need to be provided separately, however it
becomes important to supply this when there is only a callback.
\note A mapping can be associated both with a node property and a
callback. It is important however that \a type matches the type of the
property in this case. Note also that for properties of type QVariant (for
example, QParameter::value), the \a type is the type of the value stored in
the QVariant.
\note The \a callback pointer is expected to stay valid while any
associated animators are running.
