Original commit message from CVS: * gst/videotestsrc/gstvideotestsrc.c: * gst/videotestsrc/gstvideotestsrc.h: * gst/videotestsrc/videotestsrc.c: * gst/videotestsrc/videotestsrc.h: Add "colorspec" property, specifying whether to generate BT.601 or BT.709 video. This only affects YCbCr values, not RGB, since if you're generating a 709 test pattern, presumably you want 709 RGB primaries, not 601. Also add "smpte75" pattern, which uses 75% colors instead of 100%, since this is often more useful for testing (and also follows the SMPTE EG-1 guideline).
