A double buffer canvas such as CD_IUPDBUFFER is actually a CD_IUP that automatically manages an image where everything is draw and this image is drawn in the CD_IUP canvas when flush is called.
So, you can do any buffers you want but you will have to manually manage the image using cdCanvasCreateImage and a CD_IMAGE canvas to draw in the image. Notice that your main canvas can still be a CD_IUPDBUFFER.
