One can create complex control-curves by using a

computed control curves. GstLFOControlSource can generate various
computed control curves. `GstLFOControlSource` can generate various
repetitive signals. Those can be made more complex by chaining the
control sources. One can attach another control-source to e.g. modulate

In most cases GstControlBindingDirect will be the binding to be used.
In most cases `GstDirectControlBinding` will be the binding to be used.
Other control bindings are there to handle special cases, such as having
1-4 control- sources and combine their values into a single guint to
control a rgba-color property.
