Add gtk doc section Fix a bug in gst_directdraw_sink_show_frame, memcpy line by line respecting destination surface stride. * sys/directsound/gstdirectsoundplugin.c: * sys/directsound/gstdirectsoundsink.c: * sys/directsound/gstdirectsoundsink.h: Prepare the plugin to move to good: Rename all functions from gst_directsoundsink to gst_directsound_sink.
