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)
