Modify paintBox so that it draws two snowpeople side by
side. One of them should be the same height as the window; the other
should be 90% of the window height. (Snowpeople exhibit a sexual
dimorphism in which females are roughly 10% smaller than males.)
Their widths should be proportional to their heights, and their
bounding boxes should be adjacent (which means that the drawn ovals
probably will not quite touch). The pair should be centered, meaning
that there is the same amount of space on each side.
