dynamic parameter manager

<para>
|
|
The manager provides a set of functions to work with #GstElements and their #GstDParams.
|
|
One can find out which dparams an element has, get the parameter specs and
|
|
pick a control change rate.
|
|
</para>
|
|
<para>
|
|
Some functions are meant for dparam implementor (plugin writers), where others
|
|
are for applications that use elements with dparams.
