Functions
static void	open_keypad (int target, setting_id_t id)
	Opens the keypad for a set point or a setting.
static void	keypad_done (ui_keypad_result_t r, float v)
	Takes the keypad's result: applies the value or closes it.
static void	nudge (float dv, float di)
	A set point moved by dv volts and di amps, snapped to the caps.
static void	take (const touch_event_t *evt, int code)
	Takes a press: remembers its contact and what it is on.
static void	held_refused (void)
	A press on a control a programming port's hold locks: the alert band says why it takes none.
static void	down (const touch_event_t *evt)
	A contact coming down: the control under it takes the press, the output and the peaks first, whatever covers the left column.
static void	released (int was, int row, int x, int y)
	The release of the press, over the control it began on.
void	sup_drop_press (void)
	Drops the press as a lost release: a gesture asks for nothing, except a tap on OUTPUT OFF, which is sent.
static void	task_changed (void)
	The strip switched the task. A keypad open goes with the task it was opened on, typed or not, as its CANCEL does; PLOT | TABLE and the set points keep what they were. A tab switch is no navigation level.
bool	sup_safe_at (int x, int y)
	Returns whether (x, y) is on OUTPUT OFF, the one control here whose press stops what the bench drives.
void	sup_event (const touch_event_t *evt)
	Takes a touch event: presses, drags and releases on the screen's controls.
void	sup_tick (float dt_s)
	Advances the screen by one frame: holds, repeats and the question about a live output.
