+Summary: GstPropertyProbe interface
+
+patch for a GstProperty probe interface.
+
+An application may call gst_property_probe_get_list(element) to get a list
+of properties that can be probed.  Probeable properties have the type (char
+*).  At a time and in a thread appropriate to the application,
+gst_property_probe_probe_property(element,property_name) is called.  This
+function may potentially take a long time to discover possible property
+values.  After a sucessful probe_property() call, the application can call
+gst_property_probe_get_property_into() to get the list of probed property
+values.
+
+The list of probed property values is not exhaustive.  For example, probing
+for an X display may return :0 and :1, but won't (necessarily) return
+condor.ucsf.edu:0 -- however, this could still be a valid value for the
+property.
+
+This patch is slightly premature.  The prototypes for the functions are
+wrong, and the property info should be a structure with { property value,
+translatable string } pairs.
