In the activated status, the blanking width of the mixer is changed over to blanking
for analog signals. This is necessary if the signals of analogous Sources are deri-
ved. The different blanking width result in black bars on the right and left picture
edge, i.e. disturbances particularly in the case of key invert.
Note: Function Crop can also be called from other keyer menus.
