Original commit message from CVS: * gst/videotestsrc/gstvideotestsrc.c: * gst/videotestsrc/gstvideotestsrc.h: * gst/videotestsrc/videotestsrc.c: * gst/videotestsrc/videotestsrc.h: Add a test pattern called "circular", which has concentric rings with varying radial frequency. The main purpose of this pattern is to test fidelity loss in a filter or scaler element. Notably, this pattern is scale invariant, and is optimally viewed with a width (and height) of 400.
