	true where the descriptor is a terminal

Static Public Member Functions

	the terminal's foreground or background colour as 0xRRGGBB, asked with OSC 10/11 and read back from the answer; 0 where nothing answers within 150 ms
static bool	dark()
	the terminal's background, probed once at the first themed output

headless

bool dx::tty::headless{}
