Original commit message from CVS:
* gst/synaesthesia/Makefile.am:
* gst/synaesthesia/gstsynaesthesia.c:
(gst_synaesthesia_class_init), (gst_synaesthesia_init),
(gst_synaesthesia_sink_setcaps), (gst_synaesthesia_src_getcaps),
(gst_synaesthesia_chain), (plugin_init):
* gst/synaesthesia/synaescope.c:
* gst/synaesthesia/synaescope.h:
Added docs (not yet added to gst-plugins-ugl/docs/plugins as plugin is not
built by default). Fixed Makefile.am. Fixed license headers (its GPL as it
is derived from GPL code). Fixed GST_SYNAESTHESIA_CLASS macro. Added
GST_DEBUG_FUNCPTR. Reflowed _setcaps. Updated pad setup in _init. Fix
possible leak in _chain. (#356882)
