modetest: util: pattern: add new patterns
Add three new test patterns: - noise: random black and white pixels - noise-color: random color pixels - black-white: alternate between black and white pixels These patterns are useful for measuring radiated emissions for EMC compliance tests. Signed-off-by: Emil Svendsen <emas@bang-olufsen.dk>
