[Problem] PAINT-ON mode is not implemented. From the compliance tests: * RDC command has no effect except to select paint-on style. * Next data are written directly to the display upon receipt. * If other captioning is already on the screen, the four-row limit is still in effect. [Solution] It is a rare use case, we do not support overriding characters in existing cueBuilders as PAINT-ON would require. But several compliance tests check if the screen is cleared when the mode switch happens. We must keep the old captions when switching to PAINT-ON mode [Test] - Live Over-the-Air content, beginning of commercials often uses PAINT-ON mode
