GstObject

<!-- ##### SECTION Short_Description ##### -->
|

Basis for the GST object hierarchy.

<para>
|
|
GstObject provides a root for the object hierarchy tree filed in by the
|
|
GST library. It is currently a thin wrapper on top of
|
|
<classname>GtkObject</classname>, but eventually will be replaced by a
|
|
stripped down version of it. This will remove all the X dependencies from
|
|
the GST library, making it much more portably and generally useful.

<para>
|
|
GstObject gives us basic refcounting and parenting functionality, though
|
|
it is possible that we could use <classname>GtkObject</classname>'s
|
|
equivalent functions. I'll probably use what I have now until I strip
|
|
down <classname>GtkObject</classname> to re-parent the hierarchy.
