This function is very useful for functions like drawing a "clock face", a "compass" or a gauge on the LCD screen when you want to "erase" the previous dial pointer and redraw it at a new position. If you use "invert line" for the original drawing and for the "erase" drawing the two calls will cancel each other out! And it work well if the line overdraws some existing pixels -- e.g. some text on the LCD.
