Can I set the drawing mode in the application developed with WindML, such as XOR mode or copy mode, etc. If so, how can I set it? If not, then how can I solve the problem of moving targets? If there is only one target and the background color of the target is single, use the background color to paint the original position of the target and then repaint the target color in the new position of the target The movement of the target can be drawn once, but when the background of the target is not single or there are several targets superimposed together, this will leave residual points. How can I solve it?

Enable WindML double cache
One buffer drawing, one buffer display, swap buffer after drawing, so that moving target can be drawn without screen flashing
