Original commit message from CVS:
Added gst_gconf function to render visualisation plugin from GConf key "default/visualisation"
Enjoyed that commit to document those functions and remove commented functions
Original commit message from CVS:
added functions gst_gconf_get_default_{audio,video}_sink -- this is so the
defaults library (gstgconf) can be used by applications with uninstalled gstreamer
(ie, no gconf keys). More specifically, these functions enable the player to
work uninstalled, which is a good thing (tm).
