* The test pattern to produce.
*
* The Gamut pattern creates a checkerboard pattern of colors at the
* edge of the YCbCr gamut and nearby colors that are out of gamut.
* The pattern is divided into 4 regions: black, white, red, and blue.
* After conversion to RGB, the out-of-gamut colors should be converted
* to the same value as their in-gamut neighbors. If the checkerboard
* pattern is still visible after conversion, this indicates a faulty
* conversion. Image manipulation, such as adjusting contrast or
* brightness, can also cause the pattern to be visible.
*
* The Zone Plate pattern is based on BBC R&D Report 1978/23, and can
* be used to test spatial frequency response of a system. This
* pattern generator is controlled by the xoffset and yoffset parameters
* and also by all the parameters starting with 'k'. The default
* parameters produce a grey pattern. Try 'videotestsrc
* pattern=zone-plate kx2=20 ky2=20 kt=1' to produce something
* interesting.
